c++ - Linking curl after compiling fails in netbeans build -


if try this

g++ -o testapp main.cpp -i/usr/local/include -l/usr/local/lib -lcurl -lssl -lcrypto -lz -lz

it works perfect...

but if want run sample app using netbeans directly gives me errors.

here part of makefile-debug.mk

# build targets .build-conf: ${build_subprojects}     "${make}"  -f nbproject/makefile-${cnd_conf}.mk ${cnd_distdir}/${cnd_conf}/${cnd_platform}/sampleapp.exe  ${cnd_distdir}/${cnd_conf}/${cnd_platform}/sampleapp.exe: ${objectfiles}     ${mkdir} -p ${cnd_distdir}/${cnd_conf}/${cnd_platform}     ${link.cc} -i/usr/local/lib -lcurl -lssl -lcrypto -lz -lz -o ${cnd_distdir}/${cnd_conf}/${cnd_platform}/sampleapp ${objectfiles} ${ldlibsoptions}  ${objectdir}/main.o: main.cpp     ${mkdir} -p ${objectdir}     ${rm} $@.d     $(compile.cc) -g -mmd -mp -mf $@.d -o ${objectdir}/main.o main.cpp

result of netbeans build output:

what can wrong here...?

the -l option needs before library specify -l on command line.

so if need -l/usr/local/lib libcurl (as in small sample) need first specify -l correct dir , -l correct lib name.
