can anyone help me with linking libsox to my program in Windows? I have made a static library libsox.lib according to directions in INSTALL file in sox 14.2.0 source code version. Is there any way to build a dynamic library? I think it should be easier way...
What language are you using?
How are you currently building and linking the library?
This link gives some info on linking libraries in VC++ under windows, but without more info from you no-one will be able to help

I'm new to c++ and trying to run the code here https://github.com/chussong/virasoro. After installing GMP and do a "make", I got the following error. I've no idea how to fix it now. Could anybody tell me what should I look into? Is that anything wrong with my gcc? Or how can I reinstall everything on my Mac to fix any possible issues? Thank you!
As mentioned in the comment above, a likely cause of the error above is that you have not installed libgmpxx, which is a supplementary library used by GMP to provide C++ class wrappers around the basic GMP library. If you built GMP from the source provided by the developers of the library (https://gmplib.org/) you can do this by specifying the --enable-cxx option when running configure. If you installed a packaged version from some repository, you should look at that repository to see if libgmpxx is also available there.
I have a precompiled library that I have to make visible to my Cmake project, and I don't understand how I would use the package finder in Cmake to find that library. The external library itself has nothing to do with CMake. Anyone have any suggestions?
Cheers.
A few days later, I post; What ended up working for me was:
link_directories("${PROJECT_SOURCE_DIR}/ext/lib")
Where ext/lib has external precompiled libraries. I didn't want to link just to a specific target.
include_directories(path/to/my/library/headers)
target_link_libraries(myTarget path/to/my/library.so|.dll)
I would like to use XCode 4 as IDE for my C program.
I am using few libraries, which are not installed in system paths. Also, I am using external program for building (waf).
So, basically, I need XCode for everything, except building.
But I can't figure out how to tell XCode where my library include files are for it to be able to autocomplete functions and everything from that libraries?
In the build settings for the Target - look for the HEADER_SEARCH_PATHS setting.
Have you added the library headers to the project? You can just add them by reference.
I'm trying to build a simple webcam application in C++. I'm using wxWidget for GUI and OpenCV for image and video operations. But I'm having trouble setting up OpenCV on my IDE. When i try to run a sample code, or any code for that matter, I get an error that says:
ld.exe cannot find -lhighgui
I'v properly given the library and include links to the IDE. OpenCV's path is also added, I checked. I even tried linking each library file individually but id didnt work.
Please Help. :)
I'm using Windows 7 Professional X64 and Code::Blocks 10.05
Any kind of help will be appreciated.

OpenCV library files have been renamed with version 2.2. You can link to the new library opencv_highgui instead of highgui.
You also need to do this for other OpenCV libraries you use.
Pardon me if this is a "noob" question, I'm overextending myself a bit with this.
I'm trying to compile a library written in C for use in an iPhone app I'm developing. I can't seem to figure out how to do this, and I've been searching and trying things for hours.
I've tried using an External Build System project, and selecting the folder where the makefile.in.am.mingw are.
I've tried creating a Static Library project and adding the header\source files to the project. Which looked good until I tried to compile and got 260k+ errors.
When I 'cd' to the directory with the makefiles and type 'make' I get:
No targets specified and no makefile found. Stop.
I have no idea how makefiles work, I just want to use the library!
Is there a simple way to do this? If someone could at least point me in the right direction, I would be quite appreciative.
The makefiles you have are for GNU automake (under MINGW by the look of it). Even if you get them working (automake can be tricky, but it is included in Mac OS X's development thankfully), it probably won't help you much in building an iPhone library.
I did this with an existing C library by creating a new framework target in Xcode with the right include settings, etc gleaned from looking at the makefiles. That created a .framework bundle with headers and an iPhone .a library ready to be used by an iPhone project. You could also just import the C source into the iPhone project, and have it compiled in that way which would probably be quicker.
