Hi, I want to add mingw support for std::random_device and I have a few questions. 1) When configuring libstdc++, the GLIBCXX_CHECK_RANDOM_TR1 test passes successfully, because MSYS is used. But the compiler and the programs created by it can not use '/dev/urandom' || '/dev/random', because they do not use MSYS-runtime. The first question is, do I need to change the GLIBCXX_CHECK_RANDOM_TR1 test itself so that for mingw it would be not successful, or I have to add in the file 'libstdc++-v3/include/bits/random.h' an additional checking by the preprocessor and ignore the value of _GLIBCXX_USE_RANDOM_TR1 macro? I think the first variant is more logical because the second variant seems to be some cleaning up. 2) Since the I'm very new in autotools, tell me please, how should I change the GLIBCXX_CHECK_RANDOM_TR1 test? Thanks. -- Regards, niXman ___________________________________________________ Dual-target(32 & 64-bit) MinGW compilers for 32 and 64-bit Windows: http://sourceforge.net/projects/mingwbuilds/ ___________________________________________________ Another online IDE: http://liveworkspace.org/
