Bug 591202 – app-emulation/qemu[static-user] on arm: ERROR: sizeof(size_t) doesn't match GLIB_SIZEOF_SIZE_T.

• Status: RESOLVED DUPLICATE of bug 588952
• Product: Gentoo Linux

[Description Sven Müller 2016-08-13 17:03:30 UTC]

I'm trying to set up a cross-compiling environment and wanted to install qemu in user-mode.

Using the handbook:
https://wiki.gentoo.org/wiki/Embedded_Handbook/General/Compiling_with_qemu_user_chroot

I tried to compile qemu with: 

QEMU_USER_TARGETS="arm" QEMU_SOFTMMU_TARGETS="arm" USE="static-user static-libs" emerge --ask --buildpkg --oneshot qemu

and it fails with the error message:

ERROR: sizeof(size_t) doesn't match GLIB_SIZEOF_SIZE_T.
       You probably need to set PKG_CONFIG_LIBDIR
       to point to the right pkg-config files for your
       build target


To build qemu with those parameters it reinstall the packages: 
- glib
- attr
- zlib
- bzip2
with the USE-flag "-static-libs"

Additional necessary is to build: libpcre as a static lib. Then it works. So please add this constraint to the qemu-ebuild.

Can confirm the above for app-emulation/qemu-2.6.0

Also, mesa must be built with USE=gbm if opengl is enabled, which the ebuild does not check.

Of course it has to be USE="static-libs" (the minus was wrong).

dev-libs/libpcre should be also in this list:

[snip]
/usr/lib/gcc/x86_64-pc-linux-gnu/4.9.3/../../../../x86_64-pc-linux-gnu/bin/ld: cannot find -lpcre
collect2: error: ld returned 1 exit status
[/snip]

indeed ibpcre[static-libs] needed to fix this exact problem

[Comment 5 Oleh 2016-09-08 10:03:52 UTC]

COMMON_LIB_DEPEND=">=dev-libs/glib-2.0[static-libs(+)]
+       dev-libs/libpcre[static-libs(+)]
	sys-libs/zlib[static-libs(+)]
	bzip2? ( app-arch/bzip2[static-libs(+)] )
	xattr? ( sys-apps/attr[static-libs(+)] )"
is an obvious fix, please add.

[Comment 6 Matthias Maier 2016-09-09 05:24:19 UTC]

Fixed in 2.7.0-r1

this isn't a bug in qemu.  i'll revert the libpcre dep.
