WolfSSL bindings conflicting types for 'time_t' Topic is solved

[ych]

I try to build RT-STM32-LWIP-FATFS-USB-HTTPS demo from current stable_18.2.x branch and get next compile error:

Code: Select all

Hi,

Are you using GCC 7?

Giovanni

[ych]

Amm yes .

Code: Select all

$ arm-none-eabi-gcc --version
arm-none-eabi-gcc (GNU Tools for Arm Embedded Processors 7-2017-q4-major) 7.2.1 20170904 (release) [ARM/embedded-7-branch revision 255204]

Is it bad?
It seems everything except this compiles and works without any problem.

[Giovanni]

I suspect it is triggered by some change in GCC 7, could you try a lower version? not sure how to fix it, not my code.

Try to compile with GNU Arm Embedded Toolchain 4 — compiled without error, so open issue on wolfssl - https://github.com/wolfSSL/wolfssl/issues/1450.

[ych]

After prompt from WolfSSL community, I apply next patch and this issue resolver under GNU Arm Embedded Toolchain 4 and 7:

[ych]

Will this patch be applied or I need to provide some additional description?

[Giovanni]

It is fine, everything in this forum is considered for inclusion and will get at least a comment.

Fixed thanks.
