Linking apache libraries

gcc 4.4.2 c89

I am trying to link some headers and libraries in my header file. But for some reason my program doesn't seem to link.

I have in my directory src/include/apr src/libs

I have compiled the libraries and placed them in my libs and I have put the headers in the include directory.

My executable is in the src directory.

In my makefile I have specified this:

LIBS_PATH -L./lib
INC_PATH -I./include

LIBS = -libapr-1

So the current directory to where the executable is executed from.

In my lib folder I have the following library called:

libapr-1.so

And in my include/apr folder I have the following header file:

apr.h

The program is getting the header files. But I don't think it is linking the library as I don't get any errors saying that it can't find the header file.

In the file where I include the header I have done this

#include <apr/apr.h>

I do get this following error message:

In file included from include/apr.h:17,                
./include/apr/apr.h:285: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘apr_int32_t’

Many thanks for any suggestions and advice,

EDIT:

LIBS_PATH -L./lib
INC_PATH -I./include

LIBS = -lapr

Error: /usr/bin/ld: cannot find -lapr

Makefile:

OBJECT_FILES = dlg_fsm.o 

CFLAGS = -ggdb -Wall 

FLATFORM = -DLINUX

CC = gcc

LIBS_PATH = -L./lib
INC_PATH = -I./include

LIBS = -lapr

dlg: $(OBJECT_FILES)
    $(CC) $(CFLAGS) $(LDFLAGS) $(OBJECT_FILES) $(FLATFORM) $(INC_PATH) $(LIBS_PATH) $(LIBS) -o dlg

This has nothing to do with libraries, and may have nothing to do with paths. The compiler thinks there is a syntax error at the line indicated - please post that line, and the ones surrounding it, using copy and paste.

---

Once you've fixed the syntax error in your code, you'll want to change LIBS to contain -lapr-1, since the linker adds the "lib" prefix itself.

---

Either there is a syntax error in apr.h or probably apr.h expects something to be included before itself.

For example:

you write header file abc.h which uses strlen(...), but do not include string.h inside abc.h . If you want to include abc.h in file xxx.c, you have to include string.h in xxx.c before abc.h manually to make sure that abc.h has access to the declaration of strlen(...)

---

Most likely the compiler doesn't know what apr_int32_t means, whereas it should. You should post line 285 of apr.h.

Edit: I think when you say:

And in my include/apr folder I have the following header file: apr.h

that might be what's wrong. You should not have an apr.h file in your local directory—it's a file from APR. So, try renaming the file include/apr/apr.h to something else (unless by include/apr you meant your system include directory).

Edit 2:

LIBS_PATH -L./lib
INC_PATH -I./include

From the above, looks like you're in the apr source directory. Please install apr by typing make install in the apr directory, and then use the installed files in /usr/include/apr and /usr/lib/libapr* to build your program. You should not have your local source and include directories in the apr directory.
