Hi all:
I am building GNU Make 4.3 with LTO, with the following commands:
mkdir /home/rdiez/rdiez/temp/make-4.3/make-4.3-obj
cd /home/rdiez/rdiez/temp/make-4.3/make-4.3-obj
../make-4.3-src/configure CFLAGS="-g3 -O3 -march=native -flto"
--prefix="/home/rdiez/rdiez/make-4.3-bin"
make --output-sync=recurse -j "$(( $(getconf _NPROCESSORS_ONLN) + 1 ))"
make install-strip
I am getting the following warnings when compiling:
gcc -g3 -O3 -march=native -flto -Wl,--export-dynamic -o make src/ar.o src/arscan.o src/commands.o src/default.o src/dir.o src/expand.o src/file.o

src/read.o src/remake.o src/rule.o src/signame.o src/strcache.o src/variable.o src/version.o src/vpath.o src/posixos.o src/remote-stub.o

../../make-4.3-src/lib/error.h:52:13: warning: type of ‘error’ does not match
original declaration [-Wlto-type-mismatch]
../make-4.3-src/src/output.c:590:1: note: type mismatch in parameter 1
error (const floc *flocp, size_t len, const char *fmt, ...)
^
../make-4.3-src/src/output.c:590:1: note: ‘error’ was previously declared here
../make-4.3-src/src/output.c:590:1: note: code may be misoptimized unless
-fno-strict-aliasing is used
This is the declaration in error.h:
extern void error (int __status, int __errnum, const char *__format, ...)
_GL_ATTRIBUTE_FORMAT ((_GL_ATTRIBUTE_SPEC_PRINTF, 3, 4));
And this is the one in output.c:
void
error (const floc *flocp, size_t len, const char *fmt, ...)
I think one of those "error" functions should be renamed, or declared static,
or whatever.
Best regards,
rdiez
