Configuring Qt Cryptographic Architecture (QCA) ...
Verifying Qt 3.x Multithreaded (MT) build environment ... ok
Good, your configure finished. Now run 'make'.
g++ -c -pipe -Wall -W -march=k8 -O2 -pipe -D_REENTRANT -fPIC -DQT_NO_DEBUG -DQT_THREAD_SUPPORT -DQT_SHARED -DQT_TABLET_SUPPORT -march=k8 -O2 -pipe -fweb -ftracer -frename-registers -fvisibility-inlines-hidden -I/usr/qt/3/mkspecs/linux-g++ -I/var/tmp/portage/qca-1.0-r2/work/qca-1.0 -Isrc -I/usr/qt/3/include -I.ui/ -I.moc/ -o .obj/qca.o src/qca.cpp

Help. How do I fix this error? |

| Same problem here. Might come from the LDFLAGS, since it's a linker problem. Could you post yours ? |

CFLAGS="-march=k8 -O2 -pipe -fweb -ftracer -frename-registers"
CXXFLAGS="${CFLAGS} -fvisibility-inlines-hidden"
LDFLAGS="-Wl,-O1 -Wl,--enable-new-dtags -Wl,--sort-common -Wl,--strip-all"
Hope this helps. |

Ok, solved it.
I tried to compile it myself and it worked, so the problem had to come from the ebuild. I found the following workaround :
Original ebuild :
| Code: | src_compile() {
./configure --prefix=/usr || die "configure failed"
sed -i \
-e "/^CFLAGS/s:$: ${CFLAGS}:" \
-e "/^CXXFLAGS/s:$: ${CXXFLAGS}:" \
-e "/-strip/d" \
Makefile
emake || die "emake failed"
} |
I am not very good at sed, but this is doing something to the CFLAGS and CXXFLAGS, since we have a linker problem :
| Code: | src_compile() {
./configure --prefix=/usr || die "configure failed"
# sed -i \
# -e "/^CFLAGS/s:$: ${CFLAGS}:" \
# -e "/^CXXFLAGS/s:$: ${CXXFLAGS}:" \
# -e "/-strip/d" \
# Makefile
emake || die "emake failed"
}
|
Then,
| Code: | | ebuild qca-1.0-r2.ebuild digest |
It worked !
Drop me a line if it worked for you.
