Hello again,

SPDK will compile* and test ok, but when it comes time to actually install it, I get this error (solution and question at bottom):

collect2: error: ld returned 1 exit status
make[3]: *** [hello_blob] Error 1
make[2]: *** [hello_world] Error 2
make[1]: *** [blob] Error 2
make: *** [examples] Error 2

This happens regardless of whether I’ve got the compiler flag set to use SSE3/SSE4 (via ICC's “-xHost” flag) or not.

The fix is to su, run “export LDFLAGS=-lirc”, and then run “make install”. Setting LDFLAGS and then running “sudo make install” does not work.

Does this strike anyone else as a bit odd? I get needing to “sudo make install”, because non-root users don’t have write permissions in /usr/local. Seems strange that you’d need to be root just to link, though.

Thanks,

OOOOOHHHHHH……..

Yeah, that might explain a few of the “build-system quirks" I’ve been dealing with (and not just with SPDK). I was under the impression that the ‘./configure’ (or cmake, meson, etc) part would write any relevant values into either a config file or the makefiles themselves… Is that not the case? Or at least not the case with SPDK?

Thanks,

The CC, CXX, CFLAGS, and CXXFLAGS environment variables all influence the configuration, so any of them changing (e.g. due to ‘sudo’ not passing them along) will cause a rebuild during make install.  If you pass those through to the make install step, the extra LDFLAGS shouldn’t be required.

Subject: Re: [SPDK] Lots of SSE4 Link Errors in Examples, But Only When Installing

Yeah, the security angle of sudo accepting random environment variables occurred to me not long after I sent that email.

I’m not changing anything between building and installing… Here’s what I was doing before figuring out the linkage issue:
# This is where the sym link at "/opt/intel/bin/iccvars.sh" points.
source /opt/intel/parallel_studio_xe_2018.1.038/bin/psxevars.sh
prefix="/usr/local"
CC="icc"
CXX="icpc"
CFLAGS="-g -fPIC -xHost -O2 -std=c11"
CXXFLAGS="-g -fPIC -xHost -O2 -std=c++14"
# configure SPDK
./configure \
    --prefix=${prefix} \
    --with-dpdk=/usr/local
# cleanup previous builds
make -j50 clean
# build
make -j50
# run tests
./test/unit/unittest.sh
# install
sudo make install

Now, with the LDFLAGS fix, after running the test script, I do this instead:
su
export LDFLAGS=-lirc
make install
exit

LDFLAGS is only set for the final "make install" step. Even the unit tests pass without it.

Thanks,

Hi Dave,

A few observations and then some questions.

‘make install’ shouldn’t normally require a rebuild (like the re-linking you are seeing below) unless something changed in your configuration, e.g. if you are setting CFLAGS/LDFLAGS during normal compilation but not during the install step, it will rebuild since the configuration has changed.

‘sudo’ normally doesn’t pass through most environment variables for security reasons; see ‘sudo –e’ as a workaround.

I’ve added a task to our backlog to add a test machine building with ICC to the pool so we can catch these issues in automated testing: https://trello.com/c/ijL1BJIu

Do you need to set LDFLAGS=-lirc during normal ‘make’ as well, or is this just in ‘make install’?

Thanks,

Hello again,

SPDK will compile* and test ok, but when it comes time to actually install it, I get this error (solution and question at bottom):

collect2: error: ld returned 1 exit status

make[1]: *** [blob] Error 2
make: *** [examples] Error 2



This happens regardless of whether I’ve got the compiler flag set to use SSE3/SSE4 (via ICC's “-xHost” flag) or not.



The fix is to su, run “export LDFLAGS=-lirc”, and then run “make install”. Setting LDFLAGS and then running “sudo make install” does not work.



Does this strike anyone else as a bit odd? I get needing to “sudo make install”, because non-root users don’t have write permissions in /usr/local. Seems strange that you’d need to be root just to link, though.



Thanks,

Yeah, the security angle of sudo accepting random environment variables occurred to me not long after I sent that email.

I’m not changing anything between building and installing… Here’s what I was doing before figuring out the linkage issue:
# This is where the sym link at "/opt/intel/bin/iccvars.sh" points.
source /opt/intel/parallel_studio_xe_2018.1.038/bin/psxevars.sh
prefix="/usr/local"
CC="icc"
CXX="icpc"
CFLAGS="-g -fPIC -xHost -O2 -std=c11"
CXXFLAGS="-g -fPIC -xHost -O2 -std=c++14"
# configure SPDK
./configure \
    --prefix=${prefix} \
    --with-dpdk=/usr/local
# cleanup previous builds
make -j50 clean
# build
make -j50
# run tests
./test/unit/unittest.sh
# install
sudo make install

Now, with the LDFLAGS fix, after running the test script, I do this instead:
su
export LDFLAGS=-lirc
make install
exit

LDFLAGS is only set for the final "make install" step. Even the unit tests pass without it.

Thanks,
- Dave Sweeris

Hi Dave,

A few observations and then some questions.

‘make install’ shouldn’t normally require a rebuild (like the re-linking you are seeing below) unless something changed in your configuration, e.g. if you are setting CFLAGS/LDFLAGS during normal compilation but not during the install step, it will rebuild since the configuration has changed.

‘sudo’ normally doesn’t pass through most environment variables for security reasons; see ‘sudo –e’ as a workaround.

I’ve added a task to our backlog to add a test machine building with ICC to the pool so we can catch these issues in automated testing: https://trello.com/c/ijL1BJIu

Do you need to set LDFLAGS=-lirc during normal ‘make’ as well, or is this just in ‘make install’?

Thanks,
-- Daniel

Hello again,

SPDK will compile* and test ok, but when it comes time to actually install it, I get this error (solution and question at bottom):

This happens regardless of whether I’ve got the compiler flag set to use SSE3/SSE4 (via ICC's “-xHost” flag) or not.


The fix is to su, run “export LDFLAGS=-lirc”, and then run “make install”. Setting LDFLAGS and then running “sudo make install” does not work.


Does this strike anyone else as a bit odd? I get needing to “sudo make install”, because non-root users don’t have write permissions in /usr/local. Seems strange that you’d need to be root just to link, though.


Thanks,
