Posted on Edited on In ,

最近开始做MTK相关的工作，在第一步编译Modem时就遇到了挺多问题。特在此文整理和Modem相关的问题。

这种问题很好解决， 通过chmod对其提供执行权限即可。

不能定位数据库问题

提示不能定位原始codegen 数据库，错误log如下：

make[1]: *** [build/ZECHIN6737T_65_M0/LWG_DSDS_COTSX/bin/dep/codegen_dep/cgen_cfg_Modem.det] Error 2
make: *** [cgen] Error 2

此问题是因为[mt6735m_all_modem\mtk_rel\ZECHIN6737T_65_M0\LTG_DSDS\dhl\database]路径下面太多的数据库文件，只需要将多余的删除掉即可。

编译工具链问题

提示某些工具不能找到，log如下：

tools/GCC/4.6.2/linux/bin/arm-none-eabi-ld: cannot find -lnosys
tools/GCC/4.6.2/linux/bin/arm-none-eabi-ld: cannot find -lm
tools/GCC/4.6.2/linux/bin/arm-none-eabi-ld: cannot find -lc
tools/GCC/4.6.2/linux/bin/arm-none-eabi-ld: cannot find -lgcc

此问题是因为代码里面的gcc工具链有问题，需要重新安装正确的工具链，由于十分不好找，所以我上传了百度云：GCC地址。
