Compiler Can't Find Libxml/Parser.H

Compiler can't find libxml/parser.h

Try to compile with explicite inclusion where the parser.h file is, i.e. smth like this

g++ -I/usr/include/libxml2/

---

Following environment variables can also be used for lookup of header files

CPATH
C_INCLUDE_PATH
CPLUS_INCLUDE_PATH
OBJC_INCLUDE_PATH

libxml/parser.h: in c++ ubuntu

Before Posting the answer THANKS to the people who have answered, but those answers were not worked for me

I have just copied libxml folder from the directory usr/lib/libxml2 and pasted in usr/lib directory and compiled my code it is not giving any error. It is working fine now. 

code::blocks, libxml2 / libxml/parser.h: No such file or directory

In general, it's better to not move things into the mingw directories, but to leave them in their own directories, and add search paths to the project properties so it knows where to look for them.

If you go into your project properties in Code::Blocks, hit the Project build options button, then inside the Linker Settings tab, add the two libraries you're linking against. Then In the Search directories tab, add the /include to compiler search locations, and optionally, add the /lib directory to Linker locations (This isn't necessary if you gave the full path to the .a in the linker settings.

Cannot compile when using libxml

You need always to keep the -I/usr/include/libxml2 in your gcc statement, so that it can find the header files.

Problem at linking libxml2 library in my C project

As @KamilCuk pointed out in the comments, I was defining incorrectly the paths in the gcc options. So the correct command that solved the entire problem was:

gcc test.c -o test -Iinclude/ -Llib/ -l:libxml2.a

header file (.h) include problems with gcc

Actually, if the libxml2 is the system one (development package), it is probably known to pkg-config so the right way to compile and link (a single source file program) is:

 gcc -Wall -g $(pkg-config --cflags libxml-2.0) \
     ../src/code.c \
     $(pkg-config --libs libxml-2.0) \
     -o App

Of course you'll need to simply #include <libxml/parser.h> etc... as answered by alk

You really should use GNU make and have your Makefile, see this example (to adapt to C instead of C++, so CFLAGS instead of CXXFLAGS and CC instead of CXX...)

^{Take the habit to always compile with all warnings -Wall and debug info -g at least during the development phase.}

fatal error: libxml/xmlmemory.h: No such file or directory

It says CXml.h line 6 is:

#include <libxml/xmlmemory.h>

But libxml/xmlmemory.h is not in your include path. The include path is set with -I options on the compiler command line.

The error is "fatal" because compilation cannot continue past that point.

Find out where that file is actually installed and make sure the path to its libxml directory is in a -I option. For example, if it's installed in /opt/local/include/libxml/xmlmemory.h, then you need -I /opt/local/include on your command line.

CModelStereoXml, CXml and xmlmemory all are files in a library (so I can't edit it)

Only the compiled code is in a library (.a, .la, or .so file) that you can't edit. The headers will be located somewhere else.
