Error when trying to build on Archlinux under a private directory

[rancidfrog]

I get the following error when using command: make DESTDIR=~/obj install install-pywrap

utilities.c:29:18: fatal error: ustr.h: No such file or directory
compilation terminated.
Makefile:113: recipe for target 'utilities.o' failed
make[2]: *** [utilities.o] Error 1

Hello, did you install package ustr or ustr-selinux on your system? https://www.archlinux.org/packages/community/x86_64/ustr/ indicates it provides /usr/include/ustr.h.

By the way, ustr-selinux is a package that I made with custom patches because the packaged ustr library was not usable with the latest gcc the last time I checked (c.f. https://bugs.archlinux.org/task/46445)

[rancidfrog]

Thank you for the detailed response.
Will try again, as the package was missing.
Also, it seems that the BUG has been fixed according to the comment: https://bugs.archlinux.org/task/46445#comment145457

Installed ustr-selinux but got the same error as in the bug:

collect2: error: ld returned 1 exit status
Makefile:95: recipe for target 'libsemanage.so.1' failed
make[2]: *** [libsemanage.so.1] Error 1

Both ustr and ustr-selinux give same linker errors as in bug you mentioned, (multiple definition ... first defined et cetera)

[fishilico]

Did you run make clean between two build attempts?

By the way, even if https://bugs.archlinux.org/task/46445#comment145457 claims the bug is fixed, ustr package is still broken and I have not seen the patches which fix the bug in http://www.and.org/ustr/ustr.git .

I installed first ustr-selinux with yaourt from AUR, then removed package and installed ustr from Arch packages.
Yes, I realized that, as I cloned git from there and still had issues

[fishilico]

I did not understand your last comment and I managed to build the project in a Docker container, using ustr-selinux. Which system configuration are you using? (CPU, up-to-date Arch system, testing repositories?)

[rancidfrog]

I am using Arch (bbqlinux Gnome build), up-to-date, no testing repos, Intel® Core™ i7-5500U CPU
I tried to build selinux after installing ustr-selinux through Yaourt, but it did not build. I will try again.

The error I get after installing ustr-selinux from AUR:

In file included from /usr/include/ustr.h:16:0,
                 from utilities.c:29:
/usr/include/ustr-cmp.h:144:24: error: ‘ustr_cmp_case_suffix_buf_eq’ used but never defined [-Werror]

make[2]: *** [utilities.o] Error 1

[fishilico]

Indeed, I am using some patches on my system to build the project with clang and many compiler flags (for extra warnings, address sanitizer, etc.), and I forgot I added a few months ago on the first line of libsemanage/src/Makefile:

utilities.o utilities.lo genhomedircon.o genhomedircon.lo: CFLAGS += -Wno-error

... to ignore warnings generated by ustr. Moreover I changed PYTHON ?= python to PYTHON ?= python2 in policycoreutils/sepolicy/Makefile. I hope this can help you solve the issues you have.

[rancidfrog]

Adding changes to libsemanage makefiles fixed that particular issue,
but now it results in new error:

make -C test
make[2]: Entering directory '/../selinux-master/checkpolicy/test'
cc -g -Wall -W -Werror -O2 -pipe -I/../seOBJ/usr/include   -c -o dispol.o dispol.c

make[2]: *** [dispol] Error 1

Replacing "-lfl" in checkpolicy/test makefile with direct reference to "seOBJ/usr/lib//libsepol.a" results again with a new error:

xmlto man secilc.8.xml

Thank you for your time.
Seems like a hassle to compile directly.

[fishilico]

To build secilc you need to install xmlto, docbook-xml and docbook-xsl, as it specified in the PKGBUILD of the AUR package (https://github.com/archlinuxhardened/selinux/blob/master/secilc/PKGBUILD).
