SET variables and linking 3rd party LIBS
Edited by C_Worm on
I thought you were supposed to be able to set all the libraries in one or more variables but it doesn't seem to work, if i replace the libraries with the variable i get a TON of errors(ofcourse) because the compiler don't seem to link the libraries.

To be more precise: The problem occurs when i try to replace the libraries in the "cl"-command with a variable %LibVariable%

3rd Party library used: SFML

How can this be solved?
Have i got the syntax wrong somehow?

SET variables and linking 3rd party LIBS
From what I see, %winLibs% is at the wrong side of /link:

In the first code:
1
/link user32.lib gdi32.lib winmm.lib Opengl32.lib ws2_32.lib advapi32.lib


In the second code:
1
%winLibs% /link

(And I don't understand why there is "/LIBPATH:"C:\SFML\SFML-2.5.1_x64\lib"" right after /link in the second code, unless it's a typo)

When setting a variable, the spaces before the '=' become part of the variable name.

Edited by Simon Anciaux on Reason: code
To "debug" batch scripts you can remove the "@echo off" at the beginning to actually see what "code" runs.

In addition to what the others said, shouldn't that line

Removing LIBPATH or at least adding a space between the path and "sfml-system-s.lib".

SET variables and linking 3rd party LIBS
okay thanks for that, it's all about that nitty little details!

the syntax was as you pointed out wrong with the "SET varName="

However, the /LIBPATH: has to be specified at least once to locate the corret path to where the SFML-folder is right, am i right???


and here's the fixed build.bat:
