Linking to static libraries with a local DMD install

[Henry GOuk via Digitalmars-d-learn]

Hi,

Due to some security limitations, I've had to install DMD in my 
home folder on one of my university computers.

When trying to build a basic vibe.d application (i.e., the one 
created by dub init test --type=vibe.d), linking fails with a 
large number of undefined references to functions in libssl, 
libcrypto, etc.

Running dub with -v shows that the command which is failing is:

dmd 
-of.dub/build/application-debug-linux.posix-x86_64-dmd_2071-9C38B44F3C839608CC3543300CB92D81/test .dub/build/application-debug-linux.posix-x86_64-dmd_2071-9C38B44F3C839608CC3543300CB92D81/test.o ../../.dub/packages/vibe-d-0.7.29/vibe-d/libvibe-d.a ../../.dub/packages/vibe-d-0.7.29/vibe-d/libvibe-d_mail.a ../../.dub/packages/vibe-d-0.7.29/vibe-d/libvibe-d_mongodb.a ../../.dub/packages/vibe-d-0.7.29/vibe-d/libvibe-d_redis.a ../../.dub/packages/vibe-d-0.7.29/vibe-d/libvibe-d_web.a ../../.dub/packages/vibe-d-0.7.29/vibe-d/libvibe-d_diet.a ../../.dub/packages/vibe-d-0.7.29/vibe-d/libvibe-d_http.a ../../.dub/packages/vibe-d-0.7.29/vibe-d/libvibe-d_core.a ../../.dub/packages/vibe-d-0.7.29/vibe-d/libvibe-d_data.a ../../.dub/packages/vibe-d-0.7.29/vibe-d/libvibe-d_utils.a -L--no-as-needed -L-levent -L-levent_pthreads -L-lssl -L-lcrypto -g

If I then execute this command manually, with -v, then I can see 
that this command is failing:

If I try to build the same project, initialised the same way, on 
a machine with DMD and libssl, libevent, etc installed in a 
system-wide location then everything works as expected. Does 
anyone know what I've missed out when setting up DMD and the 
vibe.d dependencies?

Thanks,
Henry
