Hi,

A previous post shows how to link individual C flags with -L, but is there a convenient way of linking lots of C flags? I've tried variations of

dmd `pkg-config --libs libR` `pkg-config --cflags libR`  main.d
dmd `pkg-config --cflags --libs libR`  main.d
dmd -L`pkg-config --cflags --libs libR`  main.d
...

for linking the R library C backend on Ubuntu Linux and it hasn't worked. I'm getting the usual unrecognized switch errors:

Error: unrecognized switch '-Wl,--export-dynamic'
Error: unrecognized switch '-fopenmp'
Error: unrecognized switch '-Wl,-Bsymbolic-functions'
Error: unrecognized switch '-Wl,-z,relro'
Error: unrecognized switch '-lR'
...

If there is a method, it would be really useful to know if and how it changes for the LDC compiler and also for DUB.

Many thanks

try:

dmd "-L$(pkg-config --libs libR)" main.d

if that doesn't work there are some other tricks (with sed for example), but I think the above should work.

I pass many flags using dub.
Relevant line in my dub.json,

"name": "gparted",
	"dflags-ldc": ["--gcc=cc","--vcolumns","--oq","--dip1000","--dip25","--safe-stack-layout","--boundscheck=on","--D","--g","--w","--de","--d-debug"]

Or just direct command,

ldc2 --gcc=cc --vcolumns --oq --dip1000 --dip25 --safe-stack-layout --boundscheck=on --D --g --w --de --d-debug `find . -name \*.d -print`

Thanks
