CXX on X86 : not the correct .h file is included

[joukj]

Hi all

Since I installed CXX A10.0-230718, I get problems with packages which have their own types.h. It seems thqat CXX refuses to inlude it (see example below). This did not occur in the previous version of CXX.

In the example below the two compilations both should give an error the line "erroerror" in the .h file, but only one of them does, the other does not include it. (I also tested this with more useful content of types.h)

I have no idea if another types,.h (which??:) is included here.
Note that many opensource packages depend on their own types.h

I have no idea if another types,.h (which??:) is included here.

Probably the system include, either from SYS$COMMON:[DECC$LIB.REFERENCE.DECC$RTLDEF]TYPES.H, or - in A10.0-20230718 of the compiler - from the TYPES module in SYS$LIBRARY:DECC$RTLDEF.TLB

Note that many opensource packages depend on their own types.h

Quote from the system's TYPES.H: "Header introduced by the ISO POSIX-1 Standard".

So it's all about the search order of include files. However, a relative path in the #include should be clear. Did you try to /INCLUDE=[] ?

[joukj]

A /include=[] will not help here since the path is explicitly given in the #include "src/webp/types.h"

I realised I also got the prolem with the /include qualifier in another project

Presently I reverted back to the previous compiler.

Looks like solved i n new compiler.
