Subject: [PATCH] ibrcommon/data/File.cpp: support POSIX basename call
|
|
|
|
Firstly, and somewhat strangely, musl chooses not to provide a basename(3)
|
|
prototype within <string.h> whenever __cplusplus is defined. This can be
|
|
solved by including the <libgen.h> header defined by POSIX 1003.1 whenever
|
|
__GLIBC__ is not defined.
|
|
|
|
However, this leads to a second problem. POSIX defines the function as
|
|
char* basename(char*) and this is the only version supported by musl.
|
|
However, the std::string.cstr() method returns a const char*.
|
|
|
|
POSIX says that the string parameter can be modified. However the GNU
|
|
implementation never modifies it. glibc therefore supports an extension
|
|
when compiling under C++ by also supplying
|
|
const char* basename(const char*). This extension is not present on musl
|
|
which is the cause of the failure.
|
|
|
|
The solution is reasonably straightforward; test if __GLIBC__ is defined
|
|
before calling basename. If not, use the fallback already provided for
|
|
other platforms whereby basename() is called on a temporary copy.
