Grischka, Except the fix I've made http://repo.or.cz/tinycc.git/commitdiff/f7bfa0970e63c9290569eddf5e8aa14f614e4d5e :o)) It is *MUCH* better! Many tests now pass but few still fail, see below in bold. The const error at the end is on: extern _Thread_local const _RuneLocale *_ThreadRuneLocale; It appears that TLS (Thread Local Storage) is defined and tcc does not process this directive. Also, tcc has issues when compiled by itself. gmake -C tests gmake[1]: Entering directory '/usr/home/jullien/tinycc/tests' ------------ hello-exe ------------ ../tcc -B.. -I../include -I.. -I.. ../examples/ex1.c -o hello || (../tcc -vv; ex it 1) && ./hello Hello World ------------ hello-run ------------ ../tcc -B.. -I../include -I.. -I.. -run ../examples/ex1.c Hello World gcc -o libtcc_test libtcc_test.c ../libtcc.a -I.. -I.. -lm ------------ libtest ------------ ./libtcc_test -B.. -I../include -I.. -I..

You were clear. Anyway, maybe this helps: http://repo.or.cz/tinycc.git/commitdiff/f3c1ea6c2d7dca7883985820e46ec536e2d7e8cc It is expected that this could break system xyz whatever. Some background research: - obviously FreeBSD headers expect __GNUC__ http://pcc.ludd.ltu.se/jira/browse/PCC-18 - patch for sys/cdefs.h suggested by PCC http://pcc.ludd.ltu.se/ftp/pub/patches/openbsd-include-sys-081220.diff - __GNUC__ nowadays seems to mean the C dialect rather than the compiler https://gcc.gnu.org/ml/gcc/2008-07/msg00026.html Not sure whether we really want to define __GNUC__. This might cause all kind of problems. However if we don't then sys/cdefs.h does #define __attribute__(xyz) -- gr _______________________________________________ Tinycc-devel mailing list |
