I am using boost v1.39 libraries on Ubuntu 9.04. This is the first time I am using the boost libraries for some mathematical work. I needed to use the regularized incomplete gamma function for one of my programs. The documentation told me that gamma_q was the upper incomplete gamma function for the job. So I tried the syntax gamma_q(a,b) and I got an error saying "gamma_q was not declared in this scope". Realizing that the boost libraries were in /opt/boost, I compiled with the following : g++ ggpdf.cpp -I /opt/boost/include/boost-1_39/ I included the boost header with a #include<boost/math/special_functions/gamma.hpp>. I stil got the same error (gamma_q was not declared in scope). I then thought that I should link the libraries manually and then tried g++ ggcdf.cpp -I /opt/boost/include/boost-1_39/ -L /opt/boost/lib/ ...and still no luck. Also, the size of my /opt/boost folder is only 65M, which seems kind of small. Am I missing some incantation here for compiling or is it just an incomplete install? -- View this message in context: http://www.nabble.com/regularized-gamma-incomplete-function-%28v-1.39%29-tp2...
