I have a project in C language and it compiles just fine in visual studio without any problem. But for some reasons I need to compile it in CodeBlocks. I can't find a reason why I get this error when I build the project. This is the full build log :

I'm using CodeBlocks 10.05 and GNU GCC compiler(minGW). the project is an axis2c generated C webservice client.
I put -fPIC in Other options tab under the Compiler settings. then I rebuilt the project. as it was mentioned in CodeBlocks-wiki . I tried to run the application but I got that error again.
I have another question that I posted in This link which is related to this issue. I'd appreciate it if anyone help me.
Do you see that the linker's error message says:
C:\Tools\axis2c-bin-1.6.0-win32\lib: No such file
That is because there is no such file as C:\Tools\axis2c-bin-1.6.0-win32\lib. It is a directory, and you cannot "link a directory", just as you cannot "compile a directory".
We can be sure it is a directory because all the libraries that you are linking are in that directory:
C:\Tools\axis2c-bin-1.6.0-win32\lib\axiom.lib
C:\Tools\axis2c-bin-1.6.0-win32\lib\axutil.lib
C:\Tools\axis2c-bin-1.6.0-win32\lib\axis2_engine.lib
and also because you have specified (twice) that it is a directory that the linker should search to find libraries:
-LC:\Tools\axis2c-bin-1.6.0-win32\lib -LC:\Tools\axis2c-bin-1.6.0-win32\lib
You need to either:
Replace C:\Tools\axis2c-bin-1.6.0-win32\lib in your Link libraries settings with
C:\Tools\axis2c-bin-1.6.0-win32\lib\<name_of_some_missing_library>.lib
or, if there is no missing library (the 3 above are all you need), then:
Delete C:\Tools\axis2c-bin-1.6.0-win32\lib from your Link libraries settings
You can also delete -LC:\Tools\axis2c-bin-1.6.0-win32\lib from the Other linker options
(if that's how you've specified this linker search path), and/or you can delete
C:\Tools\axis2c-bin-1.6.0-win32\lib from Search directories -> Linker (if
that's how you've done it). You are specifying all of the axis libraries by absolute
pathnames, so there is no need to tell the linker where to look for them.
You may have also have produced this duplicated linker search path by specifying it
once in Settings -> Compiler -> Global compiler settings and again in the Linker settings or
Search directories -> Linker of your project. If so, remove it from the global compiler settings.
Those settings are ones that you want to apply to every project that you build with the compiler: that's the significance of Global.
-fPIC has no relevance whatever and you do not require it to build an .exe
I did what #Mike Kinghan said.
plus I searched and found out that the libraries that I'm using are compiled with MSVC++ and cannot be used with MinGW. according to this topic.
I created .def files with reimp
then I modified each stdcall function in .def files (I changed "_name#ordinal" to "name")
then I used dlltool to create .a files.
I linked the .a files to my project.
Everything went fine and I could compile my project. but when I try to run it. I get this error.
The procedure entry point axiom_attribute_create could not be located in the dynamic link library
I have got no idea what to do.

I have a project with a makefile, linker file and some other c files. Whenever i try to run the make command from my windows. i end up with this error. I am using a cygwin terminal. The project was initially used Linux environment.

..) failed.
make (e=2): The system cannot find the file specified.
make: *** [makefile:20: stm32init.o] Error 2
Let me know how i can fix this problem.
I am new to Makefile, C and Linux. I am using gcc & ubuntu. I encountered a problem while trying to compile the code with a link to a library.
Here is my problem. I have:
a_tests.c & b_tests.c files in "tests" folder
lib.a file in "build" folder
Here is the codes in Makefile related to the problem:
CFLAGS=-g -O2 -Wall -Wextra -Isrc -DNDEBUG $(OPTFLAGS)
TARGET=build/lib.a
TEST_SRC=$(wildcard tests/*_tests.c)
TESTS=$(patsubst %.c,%,$(TEST_SRC))
tests: CFLAGS += $(TARGET)
tests: $(TESTS)
When the tests files are compiled, "undefined reference to 'XXXfunction'"errors will be prompted. Because what executed behind is
gcc -g -O2 -Wall -Wextra -Isrc -DNDEBUG build/lib.a tests/a_tests.c -o test/a_tests
gcc -g -O2 -Wall -Wextra -Isrc -DNDEBUG build/lib.a tests/b_tests.c -o test/b_tests
But "build/lib.a" should be placed after the output file name to solve it (If I manually type in the below commands, the codes would be successfully compiled), ie:
gcc -g -O2 -Wall -Wextra -Isrc -DNDEBUG tests/a_tests.c -o test/a_tests build/lib.a
gcc -g -O2 -Wall -Wextra -Isrc -DNDEBUG tests/b_tests.c -o test/b_tests build/lib.a
But I don't know how to change in the Makefile, I tried -l -L options, they didn't work. It would warn that "cannot find the .a file". Any help would be appreciated. Thank you so much in advance!
Define the library as a dependency, because it is one. It will be appended at the end of the other dependencies, here: the source.
CFLAGS=-g -O2 -Wall -Wextra -Isrc -DNDEBUG $(OPTFLAGS)
TARGET=build/lib.a
TEST_SRC=$(wildcard tests/*_tests.c)
TESTS=$(TEST_SRC:%.c=%)
tests: $(TESTS)
$(TESTS): $(TARGET)
The library does not need to be after the output file, but after the depending input file.
The makefile is further simplified:
Replaced the patsubst with a simpler expression.
Moved the target tests up, so it is found as the first and therefore default target.
Good luck!
I'm working on a Linux project in C consisting of two different open source applications. "Project A" (libduo) creates an archive used for linking a couple test programs and creates the library like this:
/usr/bin/ar rv libduo.a duo.o http_parser.o https.o match.o parson.o urlenc.o
/usr/bin/ar: creating libduo.a
a - duo.o
a - http_parser.o
a - https.o
a - match.o
a - parson.o
a - urlenc.o
ranlib libduo.a
One of the libduo test programs is built like this:
gcc -g -O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector -I. -I. -DDUODIR=\"/usr/local/duo/libduo/etc\" -DHAVE_CONFIG_H -c test-duologin.c
gcc -o test-duologin test-duologin.o -L. -lduo -lssl -lcrypto
"Project B" is an OpenLDAP module which I've built with -lduo and a few options to tell it where to find things:
(cd .libs && rm -f pw-apr1.la && ln -s ../pw-apr1.la pw-apr1.la)

The Makefile I'm using is the same one distributed with the OpenLDAP project. I've just added a section in the Makefile to build my module, using the same options for the other modules already there but adding -lduo to my section along with the paths to the libduo includes and libduo.a.
As make suggests above, I've recompiled by adding -fPIC after the -Wall option but it the same error was repeated. As a last resort, I tried adding -static to the module build but make was having none of that either:
*** Warning: Linking the shared library pw-duo.la against the
*** static library libduo.a is not portable!
This is the first time I've tried to build a C application against a lib not in the standard Linux locations so not exactly sure what's going on. I suspect libduo is built intended to be statically linked into everything, but the OpenLDAP modules are designed to use shared libraries. Can anyone elucidate?
Update: with help of comments below and this link I created a shared library from the .o files and distributed/built against that.
I am working on a C project for Linux-environment (compiled with gcc). I am using two libraries:
SDL image (source is stored at the directory SDL_img).
SDL TTF (source is stored at the directory SDL_ttf).
My CFLAGS variable:
CFLAGS = -std=c99 -pedantic-errors -Wall -g -lm `sdl-config --cflags` -ISDL_img -ISDL_ttf
As you can see, I am including those two library-directories.
My gcc command include the following:
`sdl-config --libs` -lSDLmain -lSDL -lSDL_img -lSDL_ttf
Finally, in my project I have the following includes:
#include "SDL_ttf.h"
#include "SDL_image.h"
For some reason, I get errors of the type:
undefined reference to 'IMG_Load'
Why?
EDIT:
all: Chess.o Commons.o Console.o Controls.o Coords.o File.o GameState.o GUI.o Keyboard.o List.o Minimax.o Move.o Piece.o SettingsState.o Slots.o Square.o Str.o
gcc $^ -lm -std=c99 -pedantic-errors -g -o Chess `sdl-config --libs` -lSDLmain -lSDL -lSDL_img -lSDL_ttf
Just cd to those src/SDL_xxx dirs and do make to build those libraries and then set the correct -L and -I. It failed on linking so the -I is "good" but your path to your libraries is incorect
basically linker is now searching its paths to find libSDL_img and libSDL_ttf then it also searches /usr/lib/x86_64-linux-gnu and it still can not find it, that is why you are getting undefined referecne.
To fix this: first build those SDL_xxx and then search where are those libraries and pass somethig like this along with other to gcc:
-Lsrc/SDL_img/lib -lSDL_img -Lsrc/SDL_ttf/lib -lSDL_ttf
Can you please let me know that which flag you have build now . That you were able to generate the .gcda files now. I am using this flag for compilation .
CFLAGS_linux= -m32 -fPIC -g -pg -fprofile-arcs -ftest-coverage --coverage
and for linking I am using this
LDFLAGS_linux= -m elf_i386 -Bstatic -L/usr/lib/gcc/x86_64-redhat-linux/4.1.1/32 --whole-archive -lgcov --no-whole-archive -Bdynamic -shared -L/usr/lib -fprofile-arcs -ftest-coverage -lc
I am able to generate .gcno and my process is also coming up. But when I am trying to run the process and performing some operation the .gcda is not getting generated.
