Change your configuration to

”gcc -g -rdynamic -o marketprice.exe mp_message.o mp_config.o mp_main.o mp_kline.o mp_server.o -L ../utils -lutils -L ../network -lnetwork -Wl,-Bstatic -lev -ljansson -lmpdec -lrdkafka -lz -lssl -lcrypto -lhiredis -Wl,-Bdynamic -lcurl -lm -lpthread -ldl“

[skys215]

Add -lcurl at the end of the compile command.

if you still have any trouble, feel free to write me in telegram: @lspidh

[ilanoh]

You just changed the place at which you place -lcurl ? Why does this have any matter with the compilation ? @AddBean Were you able to resolve the issue ? @PoeticBear @skys215 I get somewhat the same error, with a lot of undefined references, no matter where I place the -lcurl. I think it may be reated to the fact that gcc don't link some libraries related to C++, but cannot find the solution at the moment.

[skys215]

My files was removed. I'm not sure, but I also added some more option while compiling, like -lrd+ or something. But I end up with using this docker image. Compiling this project by your own is such a pain.

[ilanoh]

@skys215 Can we talk in private on gitter on telegram or else ?

[cyppper]

@ilanoh you can pm me in telegram @lspidh, i will help you

[lealife]

I have run it on Centos successfully, Please see https://github.com/lealife/viabtc_exchange_server/issues/1

[ilanoh]

@lealife thanks I will check this out this weekend, were you able to play with the API as well?

I am getting the same above error. I am building libcurl for android. I have linked the crypto,openssl and curl library. Below are the libraries linking. libssl.a libcrypto.a libcurl.a I am compiling on Mac OS. Not getting what to do next.
