Bug 80384 – kdelibs emerge fails with syntax error from libxml2

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Kalen Brunham 2005-02-01 13:25:10 UTC]

When emerging kde-base/kdelibs-3.3.2-r2 I get the following error which appears to be due to syntax problems in the library libxml2.

Upon further investigation it looks like it could be caused by XMLPUBFUN not being defined, which is strange considereing xmlexports.h is included. Running gcc with -E reveals that the contents of xmlexports.h is not being included. The specific subsystem of kdelib is kdoctools.

The is a fresh install of gentoo from the 2004.3 livecd.



Reproducible: Always
Steps to Reproduce:
1. Emerge kdelib

or 

2. Emerge source for kdelib
3. ./configure
4. Make
5. or in kdoctools directory -> Make

Actual Results:

Attached is the postprocessor data from running make in kdoctools. As you can
see, xmlexports.h is never included even though it is #included in xmlversion.h
(which is #included in dict.h).

> ... -I/usr/local/include/libxml2 ...

You are compiling against something in /usr/local, that's likely to be the 
cause.

[Comment 3 Kalen Brunham 2005-02-04 05:34:16 UTC]

issue was linking against usr/local

[Comment 4 Simone Gotti (RETIRED) 2005-02-04 05:45:08 UTC]

Changing to invalid. Or should we change the checks to avoid this kind of problems (I think there are too much checks to change).

[Comment 5 Simone Gotti (RETIRED) 2005-02-04 05:46:00 UTC]

I have to write something here...
