Hi!
I’m trying to insert a timestamp in my linker Call. I modified the call to
But the check says:
i586-poky-linux-gcc.exe: error: +%s`: No such file or directory
How to define the symbol with the date?
Thx!
If you are building on Windows, please install MinGW/msys to use the Unix-style commands like ‘date’ and then specify the absolute path to the ‘date.exe’ from the msys directory so that it’s not confused with the Windows ‘date’ command.
Ok. I’ve check the command in the windows commandline with
C:\date.exe +%s
which outputs
1466065030
But I don’t know how to specify the LDFLAGS line…
I tried
- -Wl,-gc-sections,–defsym,TIMESTAMP=$(C:\date.exe +%s)
- -Wl,-gc-sections,–defsym,TIMESTAMP=
C:\date.exe +%s - -Wl,-gc-sections,–defsym,TIMESTAMP=$(“C:\date.exe” +%s)
- -Wl,-gc-sections,–defsym,TIMESTAMP=$(“C:\date.exe +%s”)
But nothing worked. I always get
- collect2.exe: error: ld returned 1 exit status
- i586-poky-linux-gcc.exe: error: +%s): No such file or directory
- i586-poky-linux-gcc.exe: error: +%s`: No such file or directory
Hi,
OK, please try the following Makefile from the command line:
test: gcc -DTIMESTAMP=$(shell C:/mingw/msys/1.0/bin/date.exe +%s) -E test.c -o test.E
You can use it with the following test.c file:
int timestamp = TIMESTAMP;
If this does not work, please let us know the error you get with this simple file. If it does, please compare the syntax here with your Makefile.
Looks like you are still trying to use your Makefile with i586-poky-linux-gcc.exe.
In order to isolate the problem please try using the minimal Makefile we provided (with the normal GCC from the MinGW toolchain and make.exe from MinGW as well). If it works, please try explicitly using the make.exe from the MinGW toolchain instead of make.exe from the i586-poky-linux toolchain.
Please start with trying this Makefile literally:
test: <TAB>gcc -DTIMESTAMP=$(shell C:/mingw/msys/1.0/bin/date.exe +%s) -E test.c -o test.E
If it works, with your make.exe, please compare the syntax in it with your Makefile that is broken. If it does not, please download a clean MinGW toolchain from here and try using make.exe and mingw-make.exe from it.
I have created a bat file in windows with the following command:
C:\Intel\iotdk-ide-win\devkit-x86\sysroots\x86_64-pokysdk-mingw32\usr\libexec\i586-poky-linux\gcc\i586-poky-linux\4.9.1\gcc.exe -DTIMESTAMP=$(shell C:/mingw/msys/1.0/bin/date.exe +%s) -E helloworld.c -o test.E
This gives me also the error:
>C:\Intel\iotdk-ide-win\devkit-x86\sysroots\x86_64-pokysdk-mingw32\usr\libexec\i586-poky-linux\gcc\i586-poky-linux\4.9.1\gcc.exe -DTIMESTAMP=$(shell C:/mingw/msys/1.0/bin/date.exe +s) -E helloworld.c -o test.E
gcc.exe: error: +s): No such file or directoryI think something with the part “$(shell C:/mingw/msys/1.0/bin/date.exe +s)” doesn’t work in Windows.
Any hints?
