| 75 | +# We could use the mpfr and gmp from the build system (since the compiler will |
| 76 | +# be run here), but there's no good way to make gcc build itself correctly if |
| 77 | +# we do. There are two main problems: |
| 78 | +# |
| 79 | +# 1. Stage2 and later cc1 and company don't honour any combination of LDFLAGS, |
| 80 | +# LDFLAGS_FOR_TARGET, BOOT_LDFLAGS, STAGE2_LDFLAGS, etc. So the only ways to |
| 81 | +# get these things built with -R/opt/local/lib are to use LD_OPTIONS which will |
| 82 | +# yield the wrong results for libraries or to hack configure. |
| 83 | +# |
| 84 | +# 2. Even if we could get -R/opt/local/lib into these programs without building |
| 85 | +# the libraries incorrectly, it would still be wrong. The pkgsrc lib directory |
| 86 | +# on many systems contains libgcc_s.so.1; however, cc1 was built by the stage2 |
| 87 | +# compiler and should find the libgcc that matches that compiler. That happens |
| 88 | +# to be the one we just built, not the pkgsrc one. |
| 89 | +# |
| 90 | +# So Instead we have mpfr and gmp built as part of the gcc build itself. |
