Cannot cross compile to Haiku with CMake

[Kartatz]

I did this

I'm porting a personal CMake project which uses curl to Haiku OS, however libcurl build is failing with the following output:

$ cmake --build ./

Looking at these logs I see curl was not able to find any socket-related function:

-- Looking for socket
-- Looking for socket - not found
-- Looking for socketpair
-- Looking for socketpair - not found
-- Looking for recv
-- Looking for recv - not found
-- Looking for send
-- Looking for send - not found
-- Looking for sendmsg
-- Looking for sendmsg - not found

But they are all properly defined in the sys/socket.h header:

$ grep --extended-regexp '(sendmsg|socketpair|socket|send|recv)\(' "${HOME}/unknown-unknown-haiku/x86_64-unknown-haiku/develop/headers/posix/sys/socket.h"
ssize_t recv(int socket, void *buffer, size_t length, int flags);
ssize_t send(int socket, const void *buffer, size_t length, int flags);
ssize_t	sendmsg(int socket, const struct msghdr *message, int flags);
int		socket(int domain, int type, int protocol);
int		socketpair(int domain, int type, int protocol, int socketVector[2]);

After a bit of research I found out Haiku requires all socket programs to link against -lnetwork (source).

So I changed the C compiler command invocation from:

-DCMAKE_C_COMPILER=${HOME}/unknown-unknown-haiku/bin/x86_64-unknown-haiku-gcc

to

-DCMAKE_C_COMPILER="${HOME}/unknown-unknown-haiku/bin/x86_64-unknown-haiku-gcc -lnetwork"

And the build went just fine.

Here is the cross compiler I used, just in case someone want to reproduce this issue.

I expected the following

Libcurl builds successful.

curl/libcurl version

I would probably suggest you try using configure instead, which is a more mature build for curl.

[renodr]

I decided to take a look at this and fix the bug real quick. 😃

You'll need to make sure that you add -DCMAKE_SYSTEM_NAME=Haiku to your CMake line, but after this commit it should build properly.

I decided to install Haiku in a VM as well and installed CMake from HaikuDepot. I discovered that running CMake on the cURL sources on Haiku will result in the same problem, so I applied my change there and it builds using your command as well (though with -DCMAKE_C_COMPILER=gcc-x86 because the default gcc is 2.95.3, which pretty much causes the build to fail immediately).

Just for fun, I decided to build curl using configure on Haiku as well, and the only thing special that I had to do was set CC=gcc-x86.

On Haiku, gcc-x86 is GCC 11.2.0, while 'gcc' is 2.95.3.

[renodr]

For users building cURL on Haiku using CMake, I suggest:

cmake -DCMAKE_C_COMPILER=gcc-x86 .

This results in a successful compilation of libcurl and the 'curl' command line utility for me
