I'm still not sure what is happening here. I do already have these
exported:
export LDFLAGS='-Wl,-rpath=/opt/lib
-Wl,--dynamic-linker=/opt/lib/ld-linux-x86-64.so.2 -L/opt/lib'
export CFLAGS='-O2 -pipe -fomit-frame-pointer -fno-caller-saves '
I added these and tried again but I got the same result:
export LD_LIBRARY_PATH='/opt/lib'
export LIBRARY_PATH='/opt/lib'
There are mostly 64 bit libraries on the system, but there are 32 bit ones
as well:
Locate doesn't exist on this machine, but 3 libcryptos are in hints:
DiskStation> ldconfig -p | grep libcrypto
libcrypto.so.1.0.0 (libc6,x86-64) => /opt/lib/libcrypto.so.1.0.0
libcrypto.so.1.0.0 (libc6) => /lib/libcrypto.so.1.0.0
libcrypto.so (libc6) => /lib/libcrypto.so
DiskStation>
How can I get configure to check for the library in the correct place? I'm
digging through the configure script. I don't find the variables for
LIBRARY_PATH or LD_LIBRARY_PATH anywhere, so i'm not sure how they would
influence things.
BTW, here is what ldd says about libcrypto. I think that does not matter,
as we just want configure to verify that it has found the correct libcrypto.
DiskStation> ldd /opt/lib/libcrypto.so.1.0.0
ldd: $warning: you do not have execution permission for
`/opt/lib/libcrypto.so.1.0.0'
linux-vdso.so.1 (0x00007fffedb11000)
libdl.so.2 => /opt/lib/libdl.so.2 (0x00007f0a72aeb000)
libc.so.6 => /opt/lib/libc.so.6 (0x00007f0a7274c000)
/opt/lib/ld-linux-x86-64.so.2 (0x00007f0a73139000)
