 Posted: Sun Oct 23, 2011 11:51 pm Post subject: [SOLVED]Ebuild to build LLVM core targeting arm-apple-darwin |
 |
|
Solved by using:
| Code: |
emake VERBOSE=1 REQUIRES_RTTI=1 || die "emake failed"
|
just like the llvm ebuild.
Outside of Portage, I can compile this perfectly fine with the same exact ./configure line that Portage will use (AFAIK):
| Code: |
CFLAGS="-march=native -msse2 -O2 -pipe" LDFLAGS="-Wl,-O1 -Wl,--as-needed" CXXFLAGS="-march=native -msse2 -O2 -pipe" ../llvmgcc42-2335.15/llvmCore/configure --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --libdir=/usr/arm-apple-darwin/usr/lib64 --target=arm-apple-darwin --prefix=/usr/arm-apple-darwin/usr --enable-optimized --disable-assertions

For some reason, -fno-rtti is passed on a file (I found a few references to RTTI in the Makefiles of the sources) and GCC (4.5.1) does not like this.

If you want to try the ebuild, you need to clone my overlay: https://github.com/tatsh/tatsh-overlay

Glad we could be of help.
