Tech Notes

When continuing to build, using automate and autoconf, I ran into this:

checking whether make sets $(MAKE)... yes
checking for gcc... gcc
checking for C compiler default output file name...
configure: error: C compiler cannot create executables
See `config.log' for more details.
make: *** [config.status] Error 77


The config.log shows:


configure:2661: checking for C compiler default output file name
configure:2688: gcc conftest.c >&5
ld: library not found for -lcrt1.10.6.o
collect2: ld returned 1 exit status


There’s a lot of discussion about this, but basically, Apple didn’t check their own tool. Shame on you, Apple.

The fix is simple, embarrassingly so:

sudo ln -s /Developer/SDKs/MacOSX10.6.sdk/usr/lib/crt1.10.6.o /Developer/usr/llvm-gcc-4.2/lib

I would expect that this needs to be updated every release.
