Too complicated... You should simply look what the command :

gcc -Wall -Wextra `xml2-config --cflags` -g -O2 `xml2-config --libs` \
-o xmlparsefile xmlparsefile-main.o

causes during the link phase. The '-v' option for GCC and '-verbose'
for the linker ('-Wl,-verbose' for GCC) are good tools for this. Just
add them somehow to the process or try the command manually with the
additions :

gcc -v -Wall -Wextra `xml2-config --cflags` -g -O2 \
`xml2-config --libs` -o xmlparsefile xmlparsefile-main.o

gcc -Wl,-verbose -Wall -Wextra `xml2-config --cflags` -g -O2 \
`xml2-config --libs` -o xmlparsefile xmlparsefile-main.o
