Bug Description

Binary package hint: usplash

Building from source fails while compiling the included svgalib:

.../usplash-0.5.49/svgalib/src/vga.c: In function 'savepalette':
.../usplash-0.5.49/svgalib/src/libvga.h:275: error: impossible constraint in 'asm'

* Compiling from a qemu armel vm
* Dependencies installed via aptitude build-dep uimage
* Build triggered via debian/rules binary
* gcc version: 4:4.4.1-1ubuntu2

It was suggested that adding -marm to the CFLAGS in debian/rules might allow the build to finish, but the build still fails with the same errors.

The failure seems to come from trying to build some x86-specific inline asm in src/svgalib.h:

static __inline__ void port_out(int value, int port)
    __asm__ volatile ("outb %0,%1"
              ::"a" ((unsigned char) value), "d"((unsigned short) port));

static __inline__ void port_outw(int value, int port)
    __asm__ volatile ("outw %0,%1"
             ::"a" ((unsigned short) value), "d"((unsigned short) port));

static __inline__ void port_outl(int value, int port)
    __asm__ volatile ("outl %0,%w1"
             ::"a" ((unsigned int)value), "Nd" ((unsigned short) port));

I meant src/libvga.h

on armel the package should use the bogl backend and not try to build svgalib parts at all(apparently it does that on the builders)

debian/rules was missing a default value for DEB_HOST_ARCH; fixed in bzr.

This bug was fixed in the package usplash - 0.5.52

usplash (0.5.52) maverick; urgency=low

  * Set DEB_HOST_ARCH if not passed in the env; LP: #568337.
  * Wrap build-deps and deps.
  * Bump up Standards-Version to 3.8.4.
  * Add ${misc:Depends}.
  * Use in Vcs-Bzr.
