Are you referring to the "Tiny C Compiler":

?

Yes, sorry if this was not clear. On debian, simply do:

$ sudo apt-get install tcc

Try the patch 1f49d725+0001-TinyCC-Add-compiler-info-for-shared-libs-on-Linux-12.patch on top of commit 1f49d725. It seems sufficient for the CMake COnly test to build (static lib, shared lib, and exec). However the resulting executable does not run:

COnly$ export LD_LIBRARY_PATH=.
COnly$ ldd ./COnly 
        linux-vdso.so.1 =>  (0x00007ffff9562000)
        libtestc2.so => ./libtestc2.so (0x00007f09f9023000)

I can build openjpeg fine (in absolutely no time). Thanks !

tcc does support debug info with -g switch:

Debugger options:
-g generate runtime debug info
-bt N show N callers in stack traces

Okay, second patch applied:

http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=ec636e29 [^]

Please take it from there to add all the other platform information as you need and send a patch with the results.

I think this hunk:

+# no optimisation in tcc:
+SET (CMAKE_C_FLAGS_INIT "")
+SET (CMAKE_C_FLAGS_DEBUG_INIT "-g")
+SET (CMAKE_C_FLAGS_MINSIZEREL_INIT "-DNDEBUG")
+SET (CMAKE_C_FLAGS_RELEASE_INIT "-DNDEBUG")
+SET (CMAKE_C_FLAGS_RELWITHDEBINFO_INIT "-g")

can go in Modules/Compiler/TinyCC-C.cmake instead because they are not platform-specific flags for the compiler. Please test that and update the patch.
