ERROR: glib-2.48 gthread-2.0 is required to compile QEMU

As reported in #40,
I have installed most of the dependencies below. I am still getting this error.
sudo apt install libglib2.0-dev libgcrypt20-dev zlib1g-dev autoconf automake libtool bison flex libpixman-1-dev libnfs-dev libiscsi-dev libaio-dev libbluetooth-dev libbrlapi-dev libbz2-dev libcap-dev libcap-ng-dev libcurl4-gnutls-dev libgtk-3-dev

Hi,
Can you show us the exact error you're getting?
I'm getting the same issue when compiling QEMU on Ubuntu 20.04 (Focal Fossa). The exact error message is the following:
cd /home/wide0s/qemu && ./configure --target-list=arm-softmmu,x86_64-softmmu && make -j2
ERROR: glib-2.48 gthread-2.0 is required to compile QEMU
make: *** [Makefile:36: qemu] Error 1
I realized that the problem is missing glib-2.48 and gthread-2.0, so that I installed glib with this command
$ apt install libglib2.0-dev
It installed version of libglib v2.64:
$ dpkg -l | grep libglib
ii libglib2.0-0:amd64 2.64.2-1~fakesync1 amd64 GLib library of C routines
ii libglib2.0-bin 2.64.2-1~fakesync1 amd64 Programs for the GLib library
ii libglib2.0-data 2.64.2-1~fakesync1 all Common files for GLib library
ii libglib2.0-dev:amd64 2.64.2-1~fakesync1 amd64 Development files for the GLib library
ii libglib2.0-dev-bin 2.64.2-1~fakesync1 amd64 Development utilities for the GLib library
However there is no libgthread2.0-dev or similar which I can install on Ubuntu 20.04 to meet this ./configure script check:
glib_req_ver=2.48
glib_modules=gthread-2.0
if test "$modules" = yes; then
glib_modules="$glib_modules gmodule-export-2.0"
fi
if test "$plugins" = yes; then
glib_modules="$glib_modules gmodule-2.0"
fi
# This workaround is required due to a bug in pkg-config file for glib as it
# doesn't define GLIB_STATIC_COMPILATION for pkg-config --static
if test "$static" = yes && test "$mingw32" = yes; then
QEMU_CFLAGS="-DGLIB_STATIC_COMPILATION $QEMU_CFLAGS"
fi
for i in $glib_modules; do
if $pkg_config --atleast-version=$glib_req_ver $i; then
glib_cflags=$($pkg_config --cflags $i)
glib_libs=$($pkg_config --libs $i)
QEMU_CFLAGS="$glib_cflags $QEMU_CFLAGS"
LIBS="$glib_libs $LIBS"
libs_qga="$glib_libs $libs_qga"
else
error_exit "glib-$glib_req_ver $i is required to compile QEMU"
fi
done
It'd be great, if someone can have a quick look on this and suggest a patch:)
I'm having the same issue.
Did you make any progress?
I stumbled too on this problem (Debian unstable) but I found a workaround (that explain the problem, by the way).
So, lets start from the beginning. Trying to build QEMU end up with:
ERROR: glib-2.48 gthread-2.0 is required to compile QEMU
I checked that gthread-2.0 was present on my distribution which was the case (install libglib2.0-dev if it is not installed).
Looking at the code of the configure leads to the following test which is failing:
#> pkg-config --atleast-version=2.48 gthread-2.0; echo $?
1
But, it seems that the pkg-config file of gthread-2.0 is installed:
#> locate gthread-2.0.pc
/usr/lib/x86_64-linux-gnu/pkgconfig/gthread-2.0.pc
So, what is missing? Well, the environment variable PKG_CONFIG_PATH can be use to force the distribution to point to the path and find the files:
#> export PKG_CONFIG_PATH=/usr/lib/x86_64-linux-gnu/pkgconfig/
#> pkg-config --atleast-version=2.48 gthread-2.0; echo $?
0
After that, this should work.
To summarize, this is definitely not a bug in the build system of QEMU. I really think that this should be reported to the maintainer of the pkg-config package in order to add /usr/lib/x86_64-linux-gnu/pkgconfig/ among the list of the default paths for pkn-config.
