Compilation errors in C++ #42

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Has this lib been tested in VS C++ environment? I tried to use it ,having all 
kind of weird (mostly language) errors coming from this lib.

Could you give some details ?

Some people reported success with compilation on Windows but I'm no specialist. 
One problem may be related to the missing glew.h header.

Well ,that is not related to OpenGL methods.Trust me I am good on this one :) I 
think may be it is because some of your headers have no extern "C" defined?  
can't currently give you exact error output as I removed the project...  it 
would be nice if your repo had a working VS C++ demo project though .Thanks.

By the way, did you try the main trunk or the gl-3.0 branch ?

Anyway, I intend to fix all pending issues quite soon, hopefully you'll be able 
to compile at that time.

No , I didn't. Btw  I am using GL 4.2 .But I ran compatible mode so that 
shouldn't be a problem.Thanks .

I just checked all the headers and they all test for cplusplus but geenrated 
arial-16.h. Maybe this was the problem.

The problem is probably MSVC not supporting C99 -- or more specifically its 
lack of support for mixed declarations and code. I had to manually go through 
and move declarations/create new scopes as necessary in order for it to 
compile, but once I did, it worked fine.

Or, as pointed out in Issue 34 (which I didn't see before now), one can choose 
to compile it as C++. When doing so it errors out on missing "round", "M_PI", 
"strndup" and "FT_Library_SetLcdFilterWeights". When compiling as C I only got 
an error on M_PI (as I just remembered), and I think 
FT_Library_SetLcdFilterWeights was missing also -- but it still compiled fine.

This is on the GL-3.0-branch.

Thanks. I fixed the M_PI and strnup in the gl-3.0 branch.

For the FT_Library_SetLcdFilterWeights you have to check if you compiled with 
subpixel rendering or not (see issuer 45).
