Bug ID: 107612
Summary: plugin/m2rte doesn't build on Mac OS X 10.7
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: modula2
Assignee: gaius at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
Target Milestone: ---
Host: x86_64-apple-darwin11.4.2
Target: x86_64-apple-darwin11.4.2
Build: x86_64-apple-darwin11.4.2
Building the current devel/modula-2 branch on Mac OS X 10.7 fails building
the m2rte plugin:
* First, compilation fails
In file included from
/vol/gcc/src/hg/master/modula-2/gcc/m2/plugin/m2rte.cc:31:
/vol/gcc/src/hg/master/modula-2/gcc/intl.h:30:10: fatal error: libintl.h: No
such file or directory
30 | #include <libintl.h>
| ^~~~~~~~~~~
There's no system libintl, but the compile command lacks $(INCINTL).
To fix this, gcc/Makefile.in needs
INCINTL = @INCINTL@
so $(INCINTL) can be used in gcc/m2/Make-lang.in. Then, the current
instances of @INCINTL@ in gcc/Makefile.in can also be replaced by $(INCINTL).
* This (done manually for now) lets the compilation succeed, but the link still
fails:

For one, the plugin may need to be linked with $(LIBINTL) (or not, don't
know for certain). Besides, according to
gcc/testsuite/lib/plugin-support.exp,
the link needs to add -undefined dynamic_lookup
