'undefined reference to symbol 'pthread_create@@GLIBC_2.2.5' while compiling bochs

Question

I'm trying to compile bochs with this command:

./configure --with-x11 --with-wx --enable-ne2000 --enable-iodebug --enable-disasm --enable-debugger --enable-e1000 --enable-usb --enable-pci

it works, but then when I run make I got:

usr/bin/ld: gui/libgui.a(gtk_enh_dbg_osdep.o): undefined reference to symbol 'pthread_create@@GLIBC_2.2.5'
/lib/x86_64-linux-gnu/libpthread.so.0: error adding symbols: DSO missing from command line

Any Help ? :/

Answer 1

You need to add -lpthread to the Makefile under LIBS

Answer 2

The problem occurs when configuring a Bochs build with --enable-debugger, and seems to be a bug in Bochs's automatic build configuration wherein it incorrectly omits -pthread from the linker flags on Linux platforms.

There is no need to edit the Makefile as suggested in the previous answer. Rather, the workaround is to specify LDFLAGS='-pthread' when configuring the build; for example:

./configure --enable-debugger LDFLAGS='-pthread'

I've filed bug report #1364 with the Bochs project. Please chime in over there to make sure the developers note and fix this bug.

cd bochs-2.4.5
sudo ./configure --enable-debugger --enable-disasm LDFLAGS='-pthread'
