Multiple definitions of functions during executable generation about seq HOT 6 OPEN

Hi @samhorsfield96. Try changing the /path/to/seq/lib to the specific path where the Seq shared libs are installed on your system. e.g. For me it is /home/mhenders/.seq/lib/seq. You could also consider setting the LD_LIBRARY_PATH variable (see here for a brief discussion).

You may also need to try it without the -no-pie option, as shown here.

Hi @markhend, thanks for such a speedy response. I am already linking directly to the seq lib directory (I changed it in the example just for readability). I am also already adding the seq lib directory to the LD_LIBRARY_PATH variable, and still run into the same issues.

I did try without -no-pie however I run into the below error:

/usr/bin/ld: foo.o: relocation R_X86_64_32 against `.bss' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: Nonrepresentable section on output
collect2: error: ld returned 1 exit status

from seq.

@samhorsfield96 I have been running the examples again and seeing the same issues as you - lots of 'multiple definition of' errors. I'm using Ubuntu (WSL) as well. Let us dig in a bit more to see if we can determine the root cause. Thank you.

@samhorsfield96, I haven't determined root cause yet. I got a little closer. Perhaps this might help you.

$ seqc build -o foo.o foo.seq --relocation-model=pic
$ gcc -shared -L/home/mhenders/.seq/lib/seq -o libfoo.so foo.o -lseqrt -lomp
$ gcc -o foo -L/home/mhenders/.seq/lib/seq -lseqrt -L. -lfoo foo.c

/usr/bin/ld: /tmp/ccXc1N7d.o: in function `main':
foo.c:(.text+0xe): undefined reference to `foo'
collect2: error: ld returned 1 exit status

from seq.

@markhend unfortunately I run into the same issue as you

/tmp/ccBJNODw.o: In function `main':
foo.c:(.text+0xa): undefined reference to `foo'
collect2: error: ld returned 1 exit status

from seq.

@markhend compiling with the -c flag gets rid of the multiple definition errors, however foo is an object and not an executable

$ seqc build -o foo.o foo.seq
$ gcc -shared -L/path/to/seq/lib -o libfoo.so foo.o -no-pie -lseqrt -lomp
$ gcc -o foo -lfoo -c foo.c
$ ./foo
-bash: ./foo: cannot execute binary file: Exec format error
