Subject: [PATCH 1/1] elftosb: force host C++ compiler
|
|
|
|
Because Freescale provides *.cpp sources and elftosb links again libstdc++,
|
|
force to use the host c++ compiler.
|
|
|
|
This patch avoids the following error occurs:
|
|
|
|
gcc AESKey.o Blob.o crc.o DataSource.o DataTarget.o ELFSourceFile.o EncoreBootImage.o EvalContext.o GHSSecInfo.o GlobMatcher.o HexValues.o Logging.o Operation.o OptionDictionary.o options.o OutputSection.o Random.o RijndaelCBCMAC.o rijndael.o SHA1.o SourceFile.o SRecordSourceFile.o stdafx.o StELFFile.o StExecutableImage.o StSRecordFile.o Value.o Version.o format_string.o ExcludesListMatcher.o SearchPath.o DataSourceImager.o IVTDataSource.o BootImageGenerator.o ConversionController.o ElftosbAST.o elftosb.o elftosb_lexer.o ElftosbLexer.o elftosb_parser.tab.o EncoreBootImageGenerator.o -lstdc++ -o elftosb

/usr/bin/ld: ElftosbAST.o: undefined reference to symbol 'powf@@GLIBC_2.2.5'
|
|
/usr/bin/ld: note: 'powf@@GLIBC_2.2.5' is defined in DSO /lib64/libm.so.6 so try adding it to the linker command line
|
|
/lib64/libm.so.6: could not read symbols: Invalid operation
|
|
collect2: error: ld returned 1 exit status
|
|
|
|
When compiling with gcc and linking against libstdc++, ld uses libc instead of
|
|
libstdc++.
|
|
However, libc does not provide all functions libstdc++ does.
|
|
Indeed, maths functions are provided by libm, not libc.
|
|
Thus, elftosb should either:
|
|
- use gcc and link against libc and libm;
|
|
- or use g++ and link against libstdc++.
|
|
|
|
Because elftosb is written in C++, this patch implement the sencond option, using
|
|
g++ and linking against libstdc++.
