Building with: export CGO_CFLAGS="-DMAGICKCORE_HDRI_ENABLE=0 -DMAGICKCORE_QUANTUM_DEPTH=16 -I/temp/imagemagick-temp/include/ImageMagick-6" export CGO_LDFLAGS="-L/temp/imagemagick-temp/lib -lMagickWand-6.Q16 -lMagickCore-6.Q16" go build -v -x -tags no_pkgconfig debug.go > debug_build_with_flags.txt 2>&1 gives the same error. > I don't see anything in this output that will tell the program where > to find the shared library. My understanding is that it was extract from the pkg-config information and passed as the -L flag CGO_LDFLAGS e.g. CGO_LDFLAGS="-g" "-O2" "-L/temp/imagemagick-temp/lib" However as that doesn't work, perhaps my understanding is wrong. cheers Dan ------- WORK=/tmp/go-build032396311 command-line-arguments mkdir -p $WORK/command-line-arguments/_obj/ mkdir -p $WORK/command-line-arguments/_obj/exe/ cd /home/github/golang/goworkspace/src/debug CGO_LDFLAGS="-L/temp/imagemagick-temp/lib" "-lMagickWand-6.Q16" "-lMagickCore-6.Q16" /home/github/golang/go/pkg/tool/linux_amd64/cgo -objdir $WORK/command-line-arguments/_obj/ -importpath command-line-arguments -- -I $WORK/command-line-arguments/_obj/ -DMAGICKCORE_HDRI_ENABLE=0 -DMAGICKCORE_QUANTUM_DEPTH=16 -I/temp/imagemagick-temp/include/ImageMagick-6 debug.go gcc -I . -fPIC -m64 -pthread -fmessage-length=0 -I $WORK/command-line-arguments/_obj/ -DMAGICKCORE_HDRI_ENABLE=0 -DMAGICKCORE_QUANTUM_DEPTH=16 -I/temp/imagemagick-temp/include/ImageMagick-6 -o $WORK/command-line-arguments/_obj/_cgo_main.o -c $WORK/command-line-arguments/_obj/_cgo_main.c gcc -I . -fPIC -m64 -pthread -fmessage-length=0 -I $WORK/command-line-arguments/_obj/ -DMAGICKCORE_HDRI_ENABLE=0 -DMAGICKCORE_QUANTUM_DEPTH=16 -I/temp/imagemagick-temp/include/ImageMagick-6 -o $WORK/command-line-arguments/_obj/_cgo_export.o -c $WORK/command-line-arguments/_obj/_cgo_export.c gcc -I . -fPIC -m64 -pthread -fmessage-length=0 -I $WORK/command-line-arguments/_obj/ -DMAGICKCORE_HDRI_ENABLE=0 -DMAGICKCORE_QUANTUM_DEPTH=16 -I/temp/imagemagick-temp/include/ImageMagick-6 -o $WORK/command-line-arguments/_obj/debug.cgo2.o -c $WORK/command-line-arguments/_obj/debug.cgo2.c gcc -I . -fPIC -m64 -pthread -fmessage-length=0 -o $WORK/command-line-arguments/_obj/_cgo_.o $WORK/command-line-arguments/_obj/_cgo_main.o $WORK/command-line-arguments/_obj/_cgo_export.o $WORK/command-line-arguments/_obj/debug.cgo2.o -L/temp/imagemagick-temp/lib -lMagickWand-6.Q16 -lMagickCore-6.Q16 /home/github/golang/go/pkg/tool/linux_amd64/cgo -objdir $WORK/command-line-arguments/_obj/ -dynpackage main -dynimport $WORK/command-line-arguments/_obj/_cgo_.o -dynout $WORK/command-line-arguments/_obj/_cgo_import.go cd $WORK gcc -I . -fPIC -m64 -pthread -fmessage-length=0 -no-pie -c trivial.c cd /home/github/golang/goworkspace/src/debug gcc -I . -fPIC -m64 -pthread -fmessage-length=0 -o $WORK/command-line-arguments/_obj/_all.o $WORK/command-line-arguments/_obj/_cgo_export.o $WORK/command-line-arguments/_obj/debug.cgo2.o -L/temp/imagemagick-temp/lib -Wl,-r -nostdlib -Wl,--build-id=none /home/github/golang/go/pkg/tool/linux_amd64/compile -o $WORK/command-line-arguments.a -trimpath $WORK -p main -buildid f97632daf57e18f83c78ba78cc2d1ac8f96a4d1f -D _/home/github/golang/goworkspace/src/debug -I $WORK -pack $WORK/command-line-arguments/_obj/_cgo_gotypes.go $WORK/command-line-arguments/_obj/debug.cgo1.go $WORK/command-line-arguments/_obj/_cgo_import.go pack r $WORK/command-line-arguments.a $WORK/command-line-arguments/_obj/_all.o # internal cd . /home/github/golang/go/pkg/tool/linux_amd64/link -o $WORK/command-line-arguments/_obj/exe/a.out -L $WORK -extld=gcc -buildmode=exe -buildid=f97632daf57e18f83c78ba78cc2d1ac8f96a4d1f $WORK/command-line-arguments.a cp $WORK/command-line-arguments/_obj/exe/a.out debug ------- -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
