How do I fix the include_next of stdlib.h from cstdlib?

Question

I'm building the Retargetable Decompiler (RetDec for short), and am coming across this error:

In file included from /usr/local/include/c++/8.2.0/ext/string_conversions.h:41,
                 from /usr/local/include/c++/8.2.0/bits/basic_string.h:6391,

make[3]: *** [Makefile:130: all] Error 2

I've dealt with this error before and have solved it, however I cannot remember how exactly I did it.

How do I fix this?

I've seen this question: Error compiling OpenCV, fatal error: stdlib.h: No such file or directory

The answers there do not help me.

Answer 1

I tried to fix this issue, but wasted 5 hours. Finally, I manually replaced #include_next with #include in three files.

• Replaced #include_next <stdlib.h> with #include <stdlib.h> in cstdlib and std_abs.h
• Replaced #include_next <math.h> with #include <math.h> in cmath

I know this is not the real fix. But I had no other way.

Edit: In my case, these files were in C:\msys64\mingw64\include\c++\<version>\
