GNU Autotools with TCC

Question

I recently discovered the Tiny C Compiler. For the project that I'm currently working on, performance is not a real issue, but file size is, making TCC ideal. I'm using Autotools as a build manager, and I figured that using TCC would be as simple as ./configure CC=tcc.

However, this returns checking whether the C compiler works... no. In config.log, it says configure: exit 77.

Despite all of this, setting CC=clang works fine. Is there any way to get Autotools to use TCC?

automake has only recently been addding support (partial) for tcc. Check if you have tools that have this support. See https://lists.gnu.org/archive/html/autotools-announce/2012-12/msg00001.html — mikijov, May 04 '13 at 23:37
My version of Autotools seems to support it. However, the issue appears to have been with my CFLAGS. — Colin Atkinson, May 05 '13 at 20:55

The issue appears to have been the fault of my CFLAGS. While TCC was normally able to compile programs with them, Autotools seems to have thought otherwise. Setting CFLAGS="" resolved the issue.

For future reference, my CFLAGS are -march=native -mtune=native -O2 -pipe -fstack-protector --param=ssp-buffer-size=4.

iirc tcc does not produce tiny executables - it is tcc itself that is tiny. Perhaps you're looking for gcc -Os?

This would probably be better as a comment than an answer. – R.. GitHub STOP HELPING ICE May 05 '13 at 15:18
Nope. TCC produces small executables, partially because of its simplicity and lack of optimization. See: http://en.wikipedia.org/wiki/Tiny_C_Compiler – Colin Atkinson May 05 '13 at 20:43
