#83 Inappropriate gcc argument order in configure script

[David von Oheimb]

When running ./configure on Linux, I got the following error:

gcc -lQtGui -lQtCore -lssl -lcrypto -lltdl -DQT_SHARED -I/usr/include/qt4 -I/usr/include/qt4/QtGui -I/usr/include/qt4/QtCore -Wall -ggdb -O2 conftest.cpp -o conftest
/tmp/cc4M6W2C.o: In function main': /home/david/sys/software/xca-0.9.3/conftest.cpp:21: undefined reference toqVersion()'
/home/david/sys/software/xca-0.9.3/conftest.cpp:21: undefined reference to SSLeay_version' /home/david/sys/software/xca-0.9.3/conftest.cpp:31: undefined reference toqVersion()'
/home/david/sys/software/xca-0.9.3/conftest.cpp:33: undefined reference to `SSLeay_version'
collect2: ld returned 1 exit status

This is because in the call of gcc, the libraries are given before the .cpp source. The problem goes away replacing

echo "${CC} $LDIRS $LIBS $CF $CFLAGS ${LDFLAGS} conftest.cpp -o conftest${SUFFIX}" >conftest.log
if ${CC} $LIBS $LDIRS $CF $CFLAGS ${LDFLAGS} conftest.cpp -o conftest${SUFFIX} >> conftest.log 2>&1; then

by

echo "${CC} $LDIRS $CF $CFLAGS ${LDFLAGS} conftest.cpp $LIBS -o conftest${SUFFIX}" >conftest.log
if ${CC} $LDIRS $CF $CFLAGS ${LDFLAGS} conftest.cpp $LIBS -o conftest${SUFFIX} >> conftest.log 2>&1; then
