I tried to run the ./configure in MSYS2 MINGW64 with mwcceppc compiler, but it is not creating executables:


$ ./configure \
  --host=powerpc-eabi \
  CC=mwcceppc.exe \
  AR=mwldeppc.exe \
  STRIP=mwldeppc.exe \
  RANLIB=mwldeppc.exe \
  --prefix=/path/to/install/wolfssl-powerpc \
  --disable-shared \
  --enable-static
configure: loading site script /etc/config.site
checking for powerpc-eabi-gcc... mwcceppc.exe
checking whether the C compiler works... no
configure: error: in `/c/Users/asn/Desktop/CryptCW/wolfssl-5.7.2':
configure: error: C compiler cannot create executables
See `config.log' for more details


As I am a beginner, I am not sure if I should be spending more time trying to make it work with mwcceppc (Freescale C/C++ Compiler for Embedded PowerPC). Am I close to make it work or should I stop trying ?

Thank you for the suggestion. These are the steps I followed:

1. Installed WSL in my Windows Machine.
2. Installed `sudo apt-get install gcc-powerpc-linux-gnu`
3. Downloaded wolfSSL from GitHub
4. Extracted and ran `./autogen.sh`
5. Then ran `./configure   --host=powerpc-linux-gnu   CC=powerpc-linux-gnu-gcc   AR=powerpc-linux-gnu-ar   STRIP=powerpc-linux-gnu-strip   RANLIB=powerpc-linux-gnu-ranlib   --prefix=/path/to/install/wolfssl-powerpc   --disable-shared   --enable-static`
6. Then I copied the library and include folder to my Windows Machine.
7. In my make file, I included this folder and library file.

I am adding these steps in case it helps someone in the future. For my case it did not work as the compiler I use is mwcceppc and the configuration I did was with GCC.

I will try to run with the ./configure command with mwcceppc compiler and update here if it works. In case there any other suggestions let me know.

Since I am using a Windows machine, I am unable to install the appropriate PowerPC cross-compiler (powerpc-linux-gnu-gcc) in Cygwin64 or MSYS2. Therefore, I assume that I will need to generate the library files on a Linux machine. I hope this assumption is correct.

Thank you for your reply.

1. Noted. Will use user_settings.h for defining configurations.

2. How do I build the static library files for PPC? I am using MSYS2 MINGW64. And where do I define the environment variable `__ppc__` to be detected in order to build wolfCrypt for PPC architecture ?

Hello,

I am using mwcceppc (Freescale C/C++ Compiler for Embedded PowerPC) in Eclipse IDE for Embedded C/C++ Developers to build a project with wolfCrypt for ST Microelectronics SPC560P Chip. I include the wolfCrypt libraries in the makefile and just add the line  #include <wolfssl/wolfcrypt/aes.h>.

Upon building the project, I get the error:

..\..\Desktop\Crypt\wolfssl-5.7.2\wolfssl\wolfcrypt\wc_port.h:828: undefined identifier 'DIR'
..\..\Desktop\Crypt\wolfssl-5.7.2\wolfssl\wolfcrypt\wc_port.h:828: (included from:
..\..\Desktop\Crypt\wolfssl-5.7.2\wolfssl\wolfcrypt\wc_port.h:828:      C:\Users\asn\Desktop\Crypt\wolfssl-5.7.2\wolfssl\wolfcrypt\types.h:35
..\..\Desktop\Crypt\wolfssl-5.7.2\wolfssl\wolfcrypt\wc_port.h:828:      C:\Users\asn\Desktop\Crypt\wolfssl-5.7.2\wolfssl\wolfcrypt\aes.h:41
..\..\Desktop\Crypt\wolfssl-5.7.2\wolfssl\wolfcrypt\wc_port.h:828:      C:\Users\asn\e_workspace\cryptoProject\application\scheduler\main.c:15)



The only change in the wolfCrypt code I have done is  #define SINGLE_THREADED in the aes.h file.


  • Any suggestion how I can resolve this ?

  • I see that in settings.h file, there is no settings for PowerPC but I believe the wolfCrypt can be used with PowerPC after a little bit of changes. I would be happy if someone can confirm this ?
