The configure script for MPFR was generated by GNU Autoconf 2.69. When I do "./configure CC=tcc", I get the following error in config.log:
[...] configure:3933: checking for gcc configure:3933: result: tcc configure:4142: checking for C compiler version configure:4164: tcc --version >&5 tcc: error: invalid option -- '--version' configure:4164: $? = 1 configure:4164: tcc -v >&5 tcc version 0.9.26 (x86-64 Linux) configure:4164: $? = 0 configure:4164: tcc -V >&5 tcc: error: invalid option -- '-V' configure:4164: $? = 1 configure:4164: tcc -qversion >&5 tcc: error: invalid option -- '-qversion' configure:4164: $? = 1 configure:4183: checking whether the C compiler works configure:4244: tcc conftest.c >&5 configure:4244: $? = 0 configure:4258: result: yes configure:4260: checking for C compiler default output file name configure:4262: result: a.out configure:4268: checking for suffix of executables configure:4298: tcc -o conftest conftest.c >&5 configure:4298: $? = 0 configure:4301: result: configure:4323: checking whether we are cross compiling configure:4359: tcc -o conftest conftest.c >&5 configure:4359: $? = 0 configure:4359: ./conftest Segmentation fault (core dumped) configure:4359: $? = 139 configure:4359: error: in `/home/vlefevre/software/mpfr': configure:4359: error: cannot run C compiled programs. If you meant to cross compile, use `--host'. See `config.log' for more details then variables and confdefs.h, but no conftest.c code. The conftest.c file is no longer there. So, it's impossible to know what's wrong. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
