Question

我尝试启动我的可执行文件，但是我收到了这个错误：

.dudac / stage / monkey / lib / hello.duda：undefined symbol：DDS_sequence_BoardGlobalParameters_BoardGPSoftState__alloc

链接和编译工作正常

这是我的makefile：

我如何解决这个问题？感谢

Answer 1

在链接期间，您指定了不在标准路径中的库

解决方案

静态链接
使用LD_LIBRARY_PATH
使用LD_PRELOAD
使用rpath

Answer 2

我尝试使用rpath就像这样但得到了同样的错误：

CFLAGS = -g -Wall -DDEBUG -L / opt / PrismTech / Vortex_v2 / Device / VortexOpenSpliceRTE / 6.7.1p2 / HDE / armv7at2_vfp_neon.WRlinux7_gcc / lib -Wl，-rpath，/ opt / PrismTech / Vortex_v2 / Device / VortexOpenSpliceRTE / 6.7.1p2 / HDE / armv7at2_vfp_neon.WRlinux7_gcc / lib -ldcpssac -ldcpsisocpp2

GCC符号查找错误
