Hello, I produce MinGW builds already about a year. In builds are used gmp+mpfr+mpc+ppl+cloog. Now I can not remember why I use ppl, and on the basis of what documentation I have come to this. Accidentally have I read the list of prerequisites for GCC and found that there is not a word about ppl, but says only about cloog and isl. But, nevertheless, I configure GCC using the option '--with-ppl', and my builds depend on libppl_c-4.dll. Therefore, I want to find out do I need to use ppl? Is there any difference what to use - ppl or cloog+isl? What is the difference? Thanks. -- Regards, niXman ___________________________________________________ Dual-target(32 & 64 bit) MinGW compilers for 32 and 64 bit Windows: http://sourceforge.net/projects/mingwbuilds/
