I'm trying to compile some source which uses libxmls I've done make -f Makefile.cvs ./configure make I get .. ..g++ -DHAVE_CONFIG_H -I. -I. -I../../.. -I../../../libwine -I../../../client/librapi -U__WCHAR_TYPE__ -D__WCHAR_TYPE__=short\ unsigned\ int -DUNICODE -O2 -fno-exceptions -fno-check-new -Wall -pedantic -W -Wpointer-arith -Wmissing-prototypes -Wwrite-strings -Wno-long-long -Wnon-virtual-dtor -fno-builtin -O2 -march=i686 -c DBBackup.cpp *Initialization*:1: warning: `__WCHAR_TYPE__' redefined DBBackup.cpp:10: libxml/tree.h: No such file or directory make[5]: *** [DBBackup.o] Error 1 make[5]: Leaving directory `/home/diddy/download/ce/synce/client/tools/DBBackup' I'm not a linux programmer, so I'm not sure how to solve this. If I look for libxml/tree.h, I can find it in. /usr/local/include/libxml2/libxml/tree.h How can I tell the compiler to include this directory ? dids
