[Solaris 11] wrong RUNPATH after install

Hello, I am building boost 1.69 on a Solaris 11.4 x86_64 box. After installation the shared libraries keep the boost dependencies from the build directory. The build log is without error and attached, ldd output is the following : :/usr/local/lib$ ldd libboost_*.so.1.69.0 libboost_chrono.so.1.69.0: bin.v2/libs/system/build/gcc-7.3.0/release/threading-multi/visibility-hidden/libboost_system.so.1.69.0 => (file not found) libstdc++.so.6 => /usr/lib/64/libstdc++.so.6 libm.so.2 => /lib/64/libm.so.2 librt.so.1 => /lib/64/librt.so.1 libgcc_s.so.1 => /usr/lib/64/libgcc_s.so.1 libpthread.so.1 => /lib/64/libpthread.so.1 libc.so.1 => /lib/64/libc.so.1 libboost_context.so.1.69.0: libstdc++.so.6 => /usr/lib/64/libstdc++.so.6 libm.so.2 => /lib/64/libm.so.2 librt.so.1 => /lib/64/librt.so.1 libgcc_s.so.1 => /usr/lib/64/libgcc_s.so.1 libpthread.so.1 => /lib/64/libpthread.so.1 libc.so.1 => /lib/64/libc.so.1 libboost_coroutine.so.1.69.0: bin.v2/libs/context/build/gcc-7.3.0/release/threading-multi/visibility-hidden/libboost_context.so.1.69.0 => (file not found) bin.v2/libs/thread/build/gcc-7.3.0/release/threadapi-pthread/threading-multi/visibility-hidden/libboost_thread.so.1.69.0 => (file not found) bin.v2/libs/chrono/build/gcc-7.3.0/release/threading-multi/visibility-hidden/libboost_chrono.so.1.69.0 => (file not found) bin.v2/libs/system/build/gcc-7.3.0/release/threading-multi/visibility-hidden/libboost_system.so.1.69.0 => (file not found) libstdc++.so.6 => /usr/lib/64/libstdc++.so.6 libm.so.2 => /lib/64/libm.so.2 librt.so.1 => /lib/64/librt.so.1 libgcc_s.so.1 => /usr/lib/64/libgcc_s.so.1 libpthread.so.1 => /lib/64/libpthread.so.1 libc.so.1 => /lib/64/libc.so.1 libboost_system.so.1.69.0: libstdc++.so.6 => /usr/lib/64/libstdc++.so.6 libm.so.2 => /lib/64/libm.so.2 librt.so.1 => /lib/64/librt.so.1 libgcc_s.so.1 => /usr/lib/64/libgcc_s.so.1 libpthread.so.1 => /lib/64/libpthread.so.1 libc.so.1 => /lib/64/libc.so.1 libboost_thread.so.1.69.0: bin.v2/libs/system/build/gcc-7.3.0/release/threading-multi/visibility-hidden/libboost_system.so.1.69.0 => (file not found) libstdc++.so.6 => /usr/lib/64/libstdc++.so.6 libm.so.2 => /lib/64/libm.so.2 librt.so.1 => /lib/64/librt.so.1 libgcc_s.so.1 => /usr/lib/64/libgcc_s.so.1 libpthread.so.1 => /lib/64/libpthread.so.1 libc.so.1 => /lib/64/libc.so.1 As a result I can't move the library on another box without changing the RUNPATH on the .so files with elfedit. I tried to build each library on it own but the final result is the same. What can I do ?

Re: [Boost-users] I ran b2 with the -d+2 command and redirected the output to a file

My project-config.jam file has quotes where needed, so that's not a problem. That file isn't the problem, but probably the commands I'm running are. I'll try to see if I can get it to work without Stacktrace. ________________________________ From: Osman Zakir <osmanzakir90(a)hotmail.com> Sent: Saturday, January 5, 2019 8:50 PM To: degski Subject: Re: [Boost-users] I ran b2 with the -d+2 command and redirected the output to a file I'll just build Boost with MSVC then, for now.

That won't help you, though [as I already gave you all the info]. Getting boost to build with clang-cl has been a long-term process [I've been pushing this for close to 2 years]. It only (mostly) works since [important work, boost 1.69] has been done by Peter Dimov (relatively recent)]. You really should dig into the archives to see what progress has been made (https://lists.boost.org/Archives/boost/2018/11/244235.php, but there are many more posts), not all might be perfect yet, we are on the bleeding edge here. The whole thing of building boost with clang-cl [as clang-cl itself, which is part of the problem, while at the same time MSVC is in significant flux as well] is a WIP (work in progress), so you cannot expect things to be perfect [yet, but the commitment is there (of all parties involved) and I am sure it will be good at some point in the (near?) future]. degski -- “If something cannot go on forever, it will stop" - Herbert Stein

Okay, so what commands did you use when building, then? When it also built Stacktrace. And could you also try with version 1.69.0 and let me know how that turns out? ________________________________ From: degski <degski(a)gmail.com> Sent: Saturday, January 5, 2019 6:40 PM To: Osman Zakir Subject: Re: [Boost-users] I ran b2 with the -d+2 command and redirected the output to a file On Sat, 5 Jan 2019 at 15:37, degski <degski(a)gmail.com<mailto:degski@gmail.com>> wrote: You need something like libboost_stacktrace_windbg_cached-vc141-mt-sgd-1_65_1.lib and libboost_stacktrace_windbg-vc141-mt-sgd-1_65_1.lib [but then for 1.69 of course and the release builds as well]. Whether that is relevant to you is for you to decide. FYI, I was able to build those libs with clang-cl. degski My guess is that the _noop_ versions do nothing [a no op(eration)], but are just stub-libs to satisfy your linker. degski -- “If something cannot go on forever, it will stop" - Herbert Stein

The Stacktrace libs I have are: "libboost_stacktrace_noop-clangw8-mt-d-x32-1_69.lib", "libboost_stacktrace_noop-clangw8-mt-d-x64-1_69.lib", "libboost_stacktrace_noop-clangw8-mt-x32-1_69.lib", and "libboost_stacktrace_noop-clangw8-mt-x64-1_69.lib" Should I have two more of the Stacktrace libs, or is this fine? As I said in my previous message, the first error actually comes from Boost.Stacktrace and it says: "error: no member named 'GetModuleFileNameA' in namespace 'boost::winapi'; did you mean simply 'GetModuleFileNameA'?". I also still need help on this issue I opened in the Boost.Asio GitHub: https://github.com/boostorg/asio/issues/184 .

This is a follow-up to the message where I asked for help about a failed attempt to build Boost. I ran b2 with the -d+2 command in addition to the other commands and also redirected the output to a file. It's attached to this message, as well as the project-config.jam file.

ASIO vs Beast DynamicBuffer use
by Cristian Morales Vega 02 Jan '19

02 Jan '19

Hi, I have just noticed that while ASIO passes DynamicBuffers as && (https://www.boost.org/doc/libs/1_68_0/doc/html/boost_asio/reference/async_r…) Beast passes them via reference (https://www.boost.org/doc/libs/1_68_0/libs/beast/doc/html/beast/ref/boost__…) I'm guessing this happens because ASIO thinks you are going to use dynamic_string_buffer/dynamic_vector_buffer as DynamicBuffer, while Beast thinks you are going to use flat_buffer/multi_buffer. In the second case doesn't make sense to give ownership of the DynamicBuffer to the initiation function because then you would not be able to look at the received data when the operation completes. Since ASIO DynamicBuffer implementations are just adaptors over string/vectors that you keep, it makes sense to move those adaptors, you still keep the string/vector with the data. Have I got it right? But this raises the question: what should I use in my own initiating functions? Regards.

function template with a universal reference to a specific type
by Ireneusz Szcześniak 01 Jan '19

01 Jan '19

Hi, I'm writing to ask a C++ question, not specifically Boost-related, but this list is the best place I know. How can I write a function template, which has a parameter of the universal reference to a specific type? I can write a function template like this: template <typename T> void foo(T &&t) { // The primary template implementation. cout << "Primary: " << __PRETTY_FUNCTION__ << endl; } And so I can call this function with an expression of any value category, and any type, cv-qualified or not, like this: int main() { foo(1); int i = 1; foo(i); const int ci = 1; foo(ci); } In my code I need to provide different implementations of foo for different types (and these types are templated). How can I accomplish that? Best, Irek

Error: no member named 'GetModuleFileNameA' in namespace 'boost::winapi'; did you mean simply 'GetModuleFileNameA'?

Hi again, everyone. When trying to build Boost 1.69.0 after having placed my installation of Python 3.7.1 above the one of Python 2.7.15, I got the error mentioned in the title of this email. It says at the end, " ...failed updating 4 targets... ...skipped 8 targets... ...updated 2381 targets... " The project-config.jam file I used is attached to this message.
