Install Error 1 & 2

[PeterJ]

I'm getting some error installing on a RedHat Linux server:

magick/log.c: In function `GetLogThreadId':
magick/log.c:751: `__NR_gettid' undeclared (first use in this function)
magick/log.c:751: (Each undeclared identifier is reported only once
magick/log.c:751: for each function it appears in.)
make[1]: *** [magick/magick_libMagickCore_la-log.lo] Error 1
make[1]: Leaving directory `/usr/local/src/ImageMagick-6.4.8-2'
make: *** [all] Error 2

Any ideas how to proceed please?

Append

• && defined(__NR_gettid)

to the line just above the return() to fix the problem you reported.

Hey thanks,

code added as required on line 750 in log.c and now these error are present:

Looks like you have two versions of the zlib headers installed which are incompatible:

• /usr/local/include/zconf.h:261: warning: redefinition of `Byte'
  /usr/include/zconf.h:214: warning: `Byte' previously declared here

You may need to uninstall the version in /usr/local/lib for ImageMagick to build.

Done and fixed.

Thank you, magick.
