[SOLVED] what include am i missing for types like u_int8_t?

Martinus2u · 03-17-2013, 08:23 AM

Tried to compile a package for cairo-dock-plugins-3.1.2 with an existing SlackBuild. It breaks like so

Code:

In file included from /usr/include/alsa/asoundlib.h:49:0,
                 from /tmp/SBo/cairo-dock-plugins-3.1.2/alsaMixer/src/applet-struct.h:23,
                 from /tmp/SBo/cairo-dock-plugins-3.1.2/alsaMixer/src/applet-init.c:20:
/usr/include/alsa/pcm.h:944:1: error: unknown type name ‘u_int8_t’
/usr/include/alsa/pcm.h:945:1: error: unknown type name ‘u_int16_t’
/usr/include/alsa/pcm.h:946:1: error: unknown type name ‘u_int32_t’
/usr/include/alsa/pcm.h:947:1: error: unknown type name ‘u_int64_t’
/usr/include/alsa/pcm.h:1052:1: error: unknown type name ‘int16_t’

I grepped /usr/include and found thoses types are used in a number of headers, but i couldn't find a definition. What am I missing?

I'm on slackware64-current and kernel 3.8.3.

Googling for 'linux gcc header u_int32_t' gives this: http://stackoverflow.com/questions/5...t-is-u-int32-t
The first link in that thread (about the duplicate post) gives more info, as does the last.

Basically they say that it appears that BSD types are being used and that you should typedef your own.

Another link from google results says that you can copy a kernel header over and use that, but it doesn't say whether the header is from BSD or Linux or Android or what: https://coderwall.com/p/2lr87q

This one from Apple gives some example typedefs: http://opensource.apple.com/source/gcc/gcc-926/stdint.h

Basic types are defined in "sys/types.h".

Thanks guys, i must have missed the line with sys/types.h.

For the record, when adding the following patch to the SlackBuild, cairo-dock-plugins-3.1.2 builds successfully.

Code:
