接触了Linux系统编程中的线程编程模块,可gcc sample.c(习惯把书上的sample代码写进sample.c文件中)出现“undefined reference to ‘pthread_create’”,所有关于线程的函数都会有此错误,导致无法编译通过。 问题的原因:pthread不是Linux下的默认的库,也就是在链接的时候,无法找到phread库中哥函数的入口地址,于是链接会...

I also see that it says the sram area has overflowed, looking at the linker files I tried shifting memory from no_cacheable to results which did remove the error but I am a little afraid to touch any of it and it did not fix the rest of the undefined reference issues ...

当你遇到“undefined reference to fork'”这样的编译错误时,通常意味着编译器在链接阶段找不到fork函数的定义。fork`函数是一个在类Unix系统(如Linux和macOS)中用于创建新进程的系统调用。以下是一些可能的原因和解决方案: 确认fork函数的来源和使用环境: fork函数是POSIX标准的一部分,因此在大多数类Unix系统中都可...
Hello OpenSSL, I've been trying to build OpenSSL version 3.2.1 on AIX 7.1 with GCC 11.3.0. The build fails with undefined references to sendmmsg which is used in crypto/bio/bss_dgram.c. The reason for this is that the sendmmsg functional...
