I have the following situation: |
2 |
- a package (valgrind) that can be compiled with PIE and uses PIE |
3 |
for some purpose or other if it is supported |
4 |
- tests (make check) that cannot be compiled with PIE |
5 |
|
6 |
In the upstream release CFLAGS is reset to "-Wno-long-long", but I would |
7 |
prefer to allow customised CFLAGS. I already asked the developers why |
8 |
they reset the CFLAGS, but I haven't received an answer. |
9 |
I made a small modification to configure to enable the use of make.conf's |
10 |
CFLAGS, but now some problems occur. The first problem is a problem even |
11 |
without this modification. |
12 |
|
13 |
If compiled with the hardened gcc profile, -fno-pie has to be specified |
14 |
when compiling the tests or it will fail. Specifying -fno-pie always |
15 |
will force me to disable any PIE support through configure as well. |
16 |
|
17 |
I tried to adapt the makefiles to disable pie themselves for the tests |
18 |
only, but then I have another problem: |
19 |
|
20 |
What if the user specifies -fpie in make.conf? |
21 |
The compilation of the tests will fail because -fpie (from the environment) |
22 |
will end up in CFLAGS after -fno-pie (from the makefile). |
23 |
If I use flag-o-matic to filter out -fpie, it will add -fno-pie everywhere |
24 |
and disable PIE altogether. |
25 |
|
26 |
I'm looking for a solution that preferably: |
27 |
- uses (some of) make.conf's CFLAGS |
28 |
- compiles with all gcc profiles and all CFLAGS (filtering some is ok) |
29 |
- does not disable PIE altogether |
30 |
|
31 |
Is there such a solution? |
