Posted on June 20, 2018 at 08:31Using latest Atollic TrueStudio (9.0.1) for STM32H743VI. From time to time, Atollic stops linking the project saying some symbols are not found. The only work around that I found is to re-create the entire workspace and the projects in it. Cleaning projects, deleting Debug directories does not help.
This situation was found with different projects and different scenarios, such as:
* A weak symbol (SysTick_Handler) defined in startup_stm32h743xx.s cannot be re-defined in the project's xxxx.s file. Removing (weak) definition from the
startup_stm32h743xx.s solves the problem
;
* Defining two symbols (functions) with the same name does not generate link error. Only re-creating the worksapce and projects solves the issue;
* Function defined in the .cpp file reported 'Not Defined' symbol by the linker. Again, only re-creating the workspace resolves the issue.
* Modifying library's source code does not necessary results in its re-building or re-linking with the referencing executable project.
Again, the conditions and steps to reproduce each time were different, the only common I could think are:
1. Troubled symbols were located in static libraries;
2. Source code for symbols were in linked folders (not in the Atollic's project directory);
3. Missing symbols reside in the same source file;
4. Using optimisation to remove dead/unreferenced code and data;
5. Using 9.0.1 version. Did not have a chance to try with other versions. Was using direct source include instead of libs before.
Any suggestions how to clean Atolic's workspace without complete re-creating all the projects from the scratch (takes almost a day) ?
