It specifically checks for the first value. I'm guessing your installer specifically checks for the second value. I don't have a proper solution, just letting you know that another installer will break. -- James Hawkins

This is probably already fixed in the git tree. See the commit: winex11.drv: Fixed the prototype of many OpenGL functions. Jesse

The test that shows that is just a couple lines up. Wine's implementation matches XP. -- James Hawkins

select() on sockets considered harmful, use poll() instead?
by Dan Kegel 01 Nov '06

01 Nov '06

This probably won't bite us for a while, but I noticed several uses of select() on sockets in the wine source code. This will fail in programs that need more than FD_SETSIZE file descriptors if one of the sockets being selected on happens to have a value of FD_SETSIZE or higher. Glibc fixes FD_SETSIZE at 1024, and does not allow this limit to be changed. Wine also uses poll(), which does not suffer from this limitation. We might want to rewrite this code to use poll() instead of select() sometime. The suspect statements are: dinput/joystick_linux.c: if (1>select(This->joyfd+1,&readfds,... dinput/joystick_linuxinput.c: if (1>select(This->joyfd+1,&readfds,... icmp/icmp_main.c: while ((res=select(icp->sid+1,&fdr,... netapi32/nbt.c: r = select(fd + 1, &fds, ... wininet/internet.c: if (select(nSocket+1,&infd,... wininet/netconnection.c: if (select(connection->socketFD+1,&infd,... ws2_32/socket.c: if( (highfd = select(highfd + 1, p_read, p_write, p_except, timeoutaddr)) Instance of select() that don't use file descriptors (i.e. that are just for delay) are safe, as are instances in conformance tests. Might make a nice little project for a new wine hacker... - Dan

Executing wine over make segfaults.
by Jimmy W 01 Nov '06

01 Nov '06

I got a simple problem, that got really hard to fix. I am trying to cross-compile stuff over a Makefile with ms compiler. Problem is that when make are executing wine as a command, wine segfaults. An example: # wine --version Works! But: Makefile --------- test: wine --version --------- Then run: #make test Wine will segfault! I have tried making a wrapper that will reset env and argv fith static values, and then exec wine with totally new variables, and still fails. Specifications: ubuntu edgy, wine 0.9.22 running as local user. Thankfull for all help. Jimmy Wennlund
