Thanks for the fast reply!
- The library is *not* pre-compiled, here's the makefile rule that produce
it :
CFLAGS ?= -std=gnu99 -Wall -Wextra -Wno-parentheses -Wno-switch
shared-lib:
$(CC) -fPIC -c $(LDFLAGS) $(CFLAGS) rj2d.c
$(CC) $(LDFLAGS) -shared -o librj2d.so.1 rj2d.o
ln -sf librj2d.so.1 librj2d.so
It seems ok to me, but there might be something missing?
- I don't think that the name "librj2d.so" is problematic however when I
remove the line INSANE_SKIP:${PN} += "dev-so" I get the following error:
ERROR: librj2d-1.1-r0 do_package_qa: QA Issue: non -dev/-dbg/nativesdk-
package librj2d contains symlink .so '/usr/lib/librj2d.so' [dev-so]
ERROR: librj2d-1.1-r0 do_package_qa: Fatal QA errors were found, failing
task.
- Here's the recipe :
SUMMARY = "RJ2D lib"
DEPENDS = ""
LICENSE = "..."
LIC_FILES_CHKSUM = "file:/..."
SRC_URI = "git://...rj2d-lib;protocol=ssh;branch=master;"
SRCREV = "..."
S = "${WORKDIR}/git"
do_compile() {
oe_runmake all
}
do_install() {
install -d ${D}${libdir}
install -m 0655 librj2d.so.1 ${D}${libdir}
ln --relative --symbolic ${D}${libdir}/librj2d.so.1
${D}${libdir}/librj2d.so
install -d ${D}${includedir}
install -m 0655 rj2d.h ${D}${includedir}/rj2d.h
}
FILES:${PN} += "${libdir}/*.so"
FILES_SOLIBSDEV = ""
INSANE_SKIP:${PN} += "dev-so"
RPROVIDES:${PN} += "librj2d.so librj2d.so()(64bit)"
That's not the first time I have this kind of problem with shared libs and
yocto, so I really wish to make it right this time !
Bests,
Yann
