[ptxdist] Iteratively Make & Make Install Subpackages

[ptxdist] Iteratively Make & Make Install Subpackages

[Chin You Wen (WMSC-HW)]

[-- Attachment #1.1: Type: text/plain, Size: 945 bytes --]

Hello,

I am compiling the SELINUX userspace tools (
https://github.com/SELinuxProject/selinux) and I encountered this error.

load_policy.c:15:25: fatal error: sepol/sepol.h: No such file or directory
compilation terminated.

The sub-package libselinux depends on libsepol, but by default the PTXDist
rule file does not run makefile sections in sequential order, i.e. it
executes the compile section for all sub-packages first, followed by
install section. This results in the required libsepol dependencies to not
be found when libselinux needs it, and thus the above error.

Is there any way to accomplish this without splitting the sub-packages into
separate rule files? I am thinking of calling something like this:

@$(call compile, libsepol)
@$(call install, libsepol)
@$(call compile, libselinux)
@$(call install, libselinux)

but I am unsure if that is possible, or what the correct syntax is. Kindly
advise. Thanks.


Regards,
You Wen

Hi,

ptxdist respects the 'select' statements in Kconfig, so you should be
able to make ptxdist build libsepol before libselinux by adding a
"select LIBSEPOL" to your "config LIBSELINUX" entry in
rules/libselinux.in. You can look at many other packages as an example,
or at this section [1] in the docs. But make sure that the 'select' is
directly in the "config LIBSELINUX" option and not in a sub-option,
otherwise the dependency parser will not find it.

[1]: https://www.ptxdist.org/doc/dev_manual.html#managing-external-compile-time-dependencies

Hope that solves your problem?

Du you have any local changes to either package? PTXdist already has the
necessary dependencies and builds as expected last time I checked.

Hi Roland/Michael,

I was able to compile it by separating the libraries (libselinux, libsepol,
libsemanag) into separate rule files and targetinstalled those dependencies
first.

However when using the repo url in a single rule file (as attached), I run
into the problem I described above.

Please explain some more, what exactly you're doing. I expected that you
use the libsepol and libselinux packages that already exist in PTXdist
(although they are pretty old).
If you have your own rules then you need to follow the instructions that
Roland mentioned.

Hi,

I am using a very old version of PTXDist (2013.01) to add SELinux support
for an old distribution. As I understand, I need to download and compile
the userland packages on my own because busybox will complain about the
absence of the 2 libraries you mentioned. The SELinux repo provides not
only these 2 libraries but also other useful tools such as SEManage.
