With C++14 the following error happens on CentOS 7.x:
==================================
$ clang++ -std=c++1y -Wall -Wextra -pedantic -Wno-missing-field-initializers \
-I. -O2 -DOSXCROSS_VERSION="\"1.2\"" -DOSXCROSS_TARGET="\"darwin14\"" \

-DOSXCROSS_LIBLTO_PATH="\"/usr/lib64/llvm\"" \
-DOSXCROSS_BUILD_DIR="\"/osxcross/build\"" -isystem quirks/include \

~~^
1 error generated.
==================================
That's a known issue with older C++ headers, see https://bugs.llvm.org/show_bug.cgi?id=30277
With C++11 we then get another problem:
==================================
$ clang++ -std=c++0x -Wall -Wextra -pedantic -Wno-missing-field-initializers \
-I. -O2 -DOSXCROSS_VERSION="\"1.2\"" -DOSXCROSS_TARGET="\"darwin14\"" \
-DOSXCROSS_OSX_VERSION_MIN="\"10.6\"" -DOSXCROSS_LINKER_VERSION="\"530\"" \
-DOSXCROSS_LIBLTO_PATH="\"/usr/lib64/llvm\"" \
-DOSXCROSS_BUILD_DIR="\"/osxcross/build\"" -isystem quirks/include \
-c -o programs/osxcross-conf.o programs/osxcross-conf.cpp
programs/osxcross-conf.cpp:50:49: error: 'auto' not allowed in lambda parameter
static auto print = [](const char *var, const auto &val) {
^~~~
programs/osxcross-conf.cpp:50:55: warning: unused parameter 'val' [-Wunused-parameter]
static auto print = [](const char *var, const auto &val) {
^
programs/osxcross-conf.cpp:54:3: error: no matching function for call to object of type '<lambda at programs/osxcross-conf.cpp:50:23>'
print("VERSION", getOSXCrossVersion());
==================================
That last issue requires a move from a lambda to more ugly
template solution. But in the end we get all built!
