Re: [Gumstix-users] bitbake errors (libgphoto and setting paths)
|
From: Marcus W <mwa...@ea...> - 2009-09-06 20:40:37

Slight update - but no resolution to my problems.
I did "bitbake libgphoto2" and after a few minutes of text scrolling across
the
screen I now have a libgphoto2.pc in the following directory:
~/gumstix/gumstix-oe/tmp/staging/arm-angstrom-linux-gnueabi/lib/pkgconfig
After that I did "ldconfig" as su, but now that I "bitbake -c rebuild
server" I
still get errors saying it can't find libgphoto2.pc.
I also tried: "export
PKG_CONFIG_PATH="${PKG_CONFIG_DIR}:~/gumstix/gumstix-oe/tmp/staging/arm-angstrom-linux-gnueabi/lib/pkgconfig"
without success
Here is an interesting note on pkg-config, but I don't know how it could
help me.
http://pkg-config.freedesktop.org/wiki/CrossCompileProposal
PKG_CONFIG_PATH does ineed not look in /usr/lib/pkgconfig (and it should
not) since there is a
libgphoto2.pc file in there. However, it should look in
~/gumstix/gumstix-oe/tmp/staging/arm-angstrom-linux-gnueabi/lib/pkgconfig
where there is indeed
a libgphoto2.pc for the gumstix (after doing bitbake libgphoto2).
supposedly CXX is used instead of CC to compile C++ files.
My Bitbake file:
=========================================================================
DESCRIPTION = "gphoto cam server program"
PR = "r0"
DEPENDS = ""
SRC_URI = " \
file://server.c \
file://myCamera.c \
file://net.c \
"
S = "${WORKDIR}"
CXXFLAGS += `pkg-config --cflags libgphoto2`
LDFLAGS += `pkg-config --libs libgphoto2`
do_compile () {
${CXX} ${CXXFLAGS} ${LDFLAGS} net.c -o net
${CXX} ${CXXFLAGS} ${LDFLAGS} myCamera.c -o myCamera
${CXX} ${CXXFLAGS} ${LDFLAGS} server.c -o server
}
do_install () {
install -d ${D}${bindir}/
install -m 0755 ${S}/server ${D}${bindir}/
}
FILES_${PN} = "${bindir}/server"
