The library is intended to be used on multiple platforms and devices. Not every single combination ofcompiler/IDE/device/library template have been, or can realistically be, checked. A set of profiles have been created for the most popular setups. If you have issues porting the library to your platform then contact me, and I will do my best to resolve anyincompatibilities. If you have no issues, or have solved it by yourself then please let me know so that I may add information about it to this page.
Visual Studio
Has been compiled under VS2019 and VS2022.
No known issues.
GCC
Has been compiled under GNU GCC on Windows & Linux.
No known issues, apart from early versions of GCC that may need to define the macro __STDC_LIMIT_MACROS in the project properties.
Keil
uVision ARM
Define the macro __STDC_LIMIT_MACROS in the project properties.
Compiled with version 5 & 6 ARM compilers.
No known issues.
TI Code ComposerMPS430
Define the macro __STDC_LIMIT_MACROS in the project properties.
In TI projects you have the choice between EABI and COFF file formats.
There is a known issue with the COFF format when creating static libraries that use templates. You may find that the linker will complain about 'undefined symbols'.
The only known workaround is to declare a dummy type in the main application that uses the template with the same parameter types.
e.g.
If your static library uses etl::vector<MyType, N> then declare a dummy type etl::vector of the same type in the application.
IAR Embedded Workbench
AVR Compiler
ARM
Define the macro __STDC_LIMIT_MACROS in the project properties.No known issues.
Segger Embedded Studio
ARM
If using STLPort then the macro ETL_STLPORT must be defined in the profile.
Greenhills
ARM
No known issues.
Zephyr OS
The ETL uses 'placement new'.
To enable this from Zephyr you need to add the following to proj.conf.
CONFIG_LIB_CPLUSPLUS=yCONFIG_NEWLIB_LIBC=y
avr-gcc 9.2
If you are using -std=c++2a you will find the compiler complaining aboutredeclaration of C++ built-in type char8_t [-fpermissive]
Add this to your etl_profile.h or define it in the project properties.
#define ETL_NO_SMALL_CHAR_SUPPORT 0
You may also want to define #define ETL_CPP20_SUPPORTED 0
Arduino
Arduino IDE
Visual Studio with Visual Micro extension
The Arduino programming platform is not supplied with an implementation of the STL. The ETL can use of somefeatures of the STL to compile, and therefore either one must be acquired or the project is compiled with ETL_NO_STL defined.
A suitable STL implementation may be downloaded from the Arduino library resource; It is called ArduinoSTL.
Add #include <ArduinoSTL.h> to the start of every file that uses the ETL.
Remember to add the directory to the include path.
The alternative option is to compile with ETL_NO_STL defined, if the STL is not used in your project.
Partially tested for Zero, Uno, Yún, Mega, Industrial 101 and Leonardo boards using test_embedded_compile.cpp
Issues
Zero
Arduino101
TinyTile
<algorithm> must be edited to move the template function iter_swap before the declaration of swap_ranges.The template class variant will not currently compile unless the header file is either renamed or the include path somehow altered, as the platform also defines a header named variant.h.
Duo
Fails to find ArduinoSTL.h even though it is present.
If ArduinoSTL.h is removed, then fails with printf has not been declared.
General
It may be necessary to add the following lines to the beginning of the file.
#undef min
#undef max
