Thanks for the replies. It compiles OK with just. However, it

I do have some versions of libcurl on my system:
/usr/lib/x86_64-linux-gnu/libcurl.so.3
/usr/lib/x86_64-linux-gnu/libcurl.so.4.3.0
/usr/lib/x86_64-linux-gnu/libcurl.so.4
I see there is a -L option to pass things to the linker
-Llinkerflag pass linkerflag to link
but I am not sure how to use it.
I've had the same problem recently. What I did was that I ran
`dmd main.d
-L-L/usr/lib/x86_64-linux-gnu/ -L-lcurl -v`. It would still
fail to link,
but I can find the linking command from the verbose output. It
was
something like this: `gcc main.o -o main -m64
-L/usr/lib/x86_64-linux-
gnu/ -lcurl -L/usr/lib/x86_64-linux-gnu -Xlinker
--export-dynamic -
l:libphobos2.a -lpthread -lm -lrt`.
As you can see, -lcurl is there, but it still needs to be added
again
after -l:libphobos2.a. So just add it again so the command
becomes:
`gcc main.o -o main -m64 -L/usr/lib/x86_64-linux-gnu/ -lcurl
-L/usr/lib/
x86_64-linux-gnu -Xlinker --export-dynamic -l:libphobos2.a
-lpthread -lm -
lrt -lcurl`. And it links and runs.
I had an additional -lcurl in already in my output, but added
another at the end:
gcc weather_report.o -o weather_report -m64
-L/usr/lib/x86_64-linux-gnu/ -lcurl -L/usr/lib/x86_64-linux-gnu
-Xlinker --export-dynamic -lcurl -l:libphobos2.a -lpthread -lm
-lrt -lcurl
but it still complains that it cannot find -lcurl. It even does
it if I add -lcurl everywhere:
gcc weather_report.o -o weather_report -m64
-L/usr/lib/x86_64-linux-gnu/ -lcurl -L/usr/lib/x86_64-linux-gnu
-Xlinker --export-dynamic -lcurl -l:libphobos2.a -lcurl -lpthread
-lcurl -lm -lrt -lcurl
As an aside, I remember having to add additional mentions of a
library in a link line years ago on Unix. I am surprised they
haven't changed the way it works so that you only have to mention
it once.
