I'll try to build a shared-linked gcc this WE to see if it does indeed has a runtime dependency against it, and see what symbols it uses. If it turns out that gcc calls no MPC symbols, then we'll remove it. > diff -r d02fbe929dc0 -r 2c95d7abdf73 config/cc/gcc.in > --- a/config/cc/gcc.in??Fri Jun 25 10:14:04 2010 +0200 > +++ b/config/cc/gcc.in??Fri Jun 25 11:02:41 2010 +0200 > @@ -131,7 +131,8 @@ > ? ? ?default n > ? ? ?select CC_GCC_4_3_or_later > ? ? ?select CC_GCC_4_2_or_later > - ? ?select CC_GCC_USE_PPL_CLOOG_MPC > + ? ?select PPL > + ? ?select CLOOG > ? > ?config CC_GCC_4_5_or_later > ? ? ?bool > @@ -140,6 +141,7 @@ > ? ? ?select CC_GCC_4_3_or_later > ? ? ?select CC_GCC_4_2_or_later > ? ? ?select CC_GCC_USE_LIBELF > + ? ?select MPC > ? > ?config CC_GCC_USE_GMP_MPFR > ? ? ?bool > @@ -147,13 +149,6 @@ > ? ? ?select GMP > ? ? ?select MPFR > ? > -config CC_GCC_USE_PPL_CLOOG_MPC > - ? ?bool > - ? ?default n > - ? ?select PPL > - ? ?select CLOOG > - ? ?select MPC If, and I say _if_, gcc does not use MPC, then why not just rename this config option and the following, move the "select MPC" down, like: config CC_GCC_4_4_or_later select CC_GCC_USE_PPL_CLOOG config CC_GCC_4_5_or_later select CC_GCC_USE_MPC_ELF config CC_GCC_USE_PPL_CLOOG blabla config CC_GCC_USE_MPC_LIBELF blabla and adapt the code in scripts/build/cc/gcc.sh accordingly? That'd be much cleaner in the end. Besides, your patch is wrong because the build script *will* try to call gcc's ./configure with --with-mpc, as the code is not based on per-lib, but is baased on the global options. Regards, Yann E.
