[ptxdist] package evtest

hi,

because I need to install an input driver for special hardware I thought I could use evtest. When including evtest in ptxdist I got a compile error with evtest-capture even it was not selected in ptxdist. The error was:

evtest-capture.c:631:39: error: expected declaration specifiers or '...' before 'xmlTextWriterPtr'
evtest-capture.c: In function 'print_capabilities':
evtest-capture.c:647:4: error: 'writer' undeclared (first use in this function)
evtest-capture.c:647:4: note: each undeclared identifier is reported only once for each function it appears in

...
I could find out that a package libxml-dev is required to use evtest-capture by trying to compile it at hand and getting:
evtest-capture.c:33:29: fatal error: libxml/encoding.h: No such file or directory
compilation terminated.

evtest itself compiles an runs on the target.

Best regards

Henrik

What PTXdist revision do you are using?

I tested it here with PTXdist-2013.03.0 for a quick test: with
PTXCONF_EVTEST_CAPTURE=n I got:

[...]

So, the "evtest-capture.c" source is not compiled in this case.

With PTXCONF_EVTEST_CAPTURE=y it changes to:

[...]

Either disable EVTEST_CAPTURE or enable LIBXML2_WRITER. There is a
dependency missing here. This is fixed in newer ptxdist versions.

Thanks for your replay. The post was only thought to be informational.
<prompt> ptxdist --version
2011.10.0

BSP is BSP-Phytec-phyCARD-L-PD12.0.1 and libxml2 is selected, but there is no -dev version and so there are no include files which causes the error.

But as I suggested I'm satisfied with localy compiled evtest.

Yours Henrik
