I wasn't aware of this subtelty... it seems so wrong to me...
But anyway, indeed the "instructions" that set these variables inside the
Makefile are kind of skipped.
I'll have to read some docs on that topic.
So no need to patch the Makefile.
I did a fast try on an unclean build directory (and with GHDL installed on my
machine...) and it seems this command works fine:
make \
GHDL="${srcdir}/gcc-build/gcc/ghdl" \
ANALYZE_OPTS="--GHDL1=${srcdir}/gcc-build/gcc/ghdl1" \
STD_GHDL_FLAGS="--GHDL1=${srcdir}/gcc-build/gcc/ghdl1" \
ghdllib
So no need to split build of libraries and of runtime...
I'll rebuild with no ghdl installed and with clean build directory, but
tomorrow I think.

Adrien

Thank you for the instructions.
1) Compile gcc with normal make in the gcc build dir
2) Patch the Makefile in the ghdl source directory (see attached patch)
3) Build libraries with that command:
make \
GHDL="${srcdir}/gcc-build/gcc/ghdl" \
ANALYZE_OPTS="--GHDL1=${srcdir}/gcc-build/gcc/ghdl1" \
STD_GHDL_FLAGS="--GHDL1=${srcdir}/gcc-build/gcc/ghdl1" \
vhdl.libs.all libs.vhdl.standard
4) Built grt: make libgrt.a
5) Install gcc and libraries as described in file BUILD.txt
So I patch the Makefile to be able to manually set the variables ANALYZE_OPTS
and STD_GHDL_FLAGS from my build script.
And I have to split the original command "make ghdllib" into the steps 3) and
4) because otherwise the path the GHDL is overwritten.
Are you sure you need to comment out ANALYZE_OPTS and STD_GHDL_FLAGS ?
Usually, Makefile variables set on the command line overrides the
definitions.
Maybe I should change the BUILD.txt ?

Re: [Ghdl-discuss] GCC flavour: Problem with compilation of VHDL libs
Ah, I still had a ghdl version installed on my system and some errors were
hidden:
When just making the target libs.vhdl.standard I get this error:
[adrien] > make
GHDL=/home/adrien/Dev/AUR/ghdl-gcc-git/pkg/ghdl-gcc-git/usr/bin/ghdl
libs.vhdl.standard
cd lib/ghdl/v93/std; \

--bootstrap-standard --std=93

problem: lib/gcc/x86_64-unknown-linux-gnu/4.9.3/ghdl1 not found
make: *** [Makefile:351: lib/ghdl/v93/std/std_standard.o] Error 1
I'll find a workaround for that, force my GHDL path for this target, and report
the result.

I thought so, so I did the ghdl fake-install with
make DESTDIR="${pkgdir}" install
and used the ghdl "installed" there to launch build of libs with
make GHDL="${pkgdir}/usr/bin/ghdl" vhdl.libs.all libs.vhdl.standard
(command line taken from inside Makefile, to set my own path to ghdl)
And compilation of libs does launch, but I get these errors:

I have also stumbled over this issue: violating the good triple-rule: configure / make / make install. Building of ghdl is already more complex due to unpacking of gcc and calling make copy-sources (though this could be treated as bootstrap and maybe better renamed to bootstrap, while preserving comment "copy sources"?). The other thing is that ghdl was nicely built out-of-tree in the gcc build directory but now make ghdllib must be called in the ghdl source directory, which I'd like to avoid. Sorry, I haven't addressed this issue right on July/August. Actually using already compiled parts to generate something else during build is not uncommon. But in such cases Makefile uses executables in their build path, not installed one. Hopefully this could be fixed. And the other thing would be to add something like make copy-ghdllib-sources to build it out-of-tree also? BTW, is there any good reason to not build ghdllib in the gcc build directory?
