Re: [fpc-devel] I have created a openocd debugger-interface for lazarus, now some questions

Hi Martin, Thank you for your detailed answers and for pointing me to the testcases. I am having a look at the breakpoint code and will see what I can do so that debugging works with only a limited number of available breakpoints. One more thing, do you know why ExecuteCommand is defined as p

Re: [fpc-devel] Why FreeBSD sem_init() works different to Linux?

Hello, You can use some structure to lock an integer. `Some structure` can for example be a mutex, a critical section, some busy waiting loop based on CMPXCH, etc... Say that you lock the integer by calling `Lock;` and you unlock it by calling `UnLock;`. Then you can define a class TSemaphore like

Hi, OK, now that we established that semaphores are broken in FreeBSD using FPC 2.6.0 and the upcoming FPC 2.6.2. I'm looking for an alternative. An alternative for two reasons. - I hate IFDEF code, and the semaphore code between Linux, FreeBSD and Windows are different. - Semaphore sem_t
