Tech on C&P

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.

Like everyone else, my Xcode install broke the command-line tools I use very often. It seems Apple didn’t feel like testing their command line stuff at all, since it’s glaringly obvious that it fails:


autoreconf: Entering directory `.'
autoreconf: configure.ac: not using Gettext
autoreconf: running: aclocal --force
autom4te: m4sugar/m4sugar.m4: no such file or directory
aclocal: /Developer/usr/bin/autom4te failed with exit status: 1
autoreconf: aclocal failed with exit status: 1


I mean “works” and “fails”, polar opposites, clearly no one checked. Shame on you, Apple.

The fix was simple: (Thanks to Nathan Herring’s consideration of ADL’s post in Stack Exchange )
