Build fails common/TracySystem.cpp:258:21: error: expected ')' before 'PRIu32'

Trying to build Tracy targeting an embedded device, using a cross-compiler

gcc-5.2.0
glibc-2.17

[TracyClient.cpp] compiling..
In file included from TracyClient.cpp:14:0:

I've searched for this error but couldn't find anyone having the same issue. Any ideas?

I was able to work around this issue by defining:

#define __STDC_FORMAT_MACROS 1

Before #include <inttypes.h>

Inside TracySystem.cpp

This seems to be a defect in the compiler. The C++11 standard (N3337) states in 27.9.2.3:

Table 135 describes header <cinttypes>. [ Note: The macros defined by <cinttypes> are provided uncon-
ditionally. In particular, the symbol __STDC_FORMAT_MACROS, mentioned in footnote 182 of the C standard,
plays no role in C++. — end note ]

Consider adding -D__STDC_FORMAT_MACROS=1 to your build system as a workaround.
