I have an Acer Aspire One A150 running the 4.8.17-hardened-r2 kernel on an Intel Atom N270. I am trying to install mono-basic in order to compile an app written in Visual Basic, and I am getting the following error. All I can find on the internet to fix it is this Xamarin bug report that suggests me to use a more recent version of Mono, which is not possible because mono-basic depends on mono-2.10.9-r2.Next is the error I get, my emerge -pqv and my emerge --info. i686-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I../.. -I../../eglib/src -I../../eglib/src -I../..  -DGC_LINUX_THREADS -D_GNU_SOURCE -D_REENTRANT -DUSE_MMAP -DUSE_MUNMAP -D_FILE_OFFSET_BITS=64 -D__default_codegen__ -DUSE_COMPILER_TLS  -O2 -march=native -pipe -fno-strict-aliasing -fno-strict-aliasing -Wdeclaration-after-statement -Wno-unused-but-set-variable -g -Wall -Wunused -Wmissing-prototypes -Wmissing-declarations -Wstrict-prototypes  -Wmissing-prototypes -Wnested-externs -Wpointer-arith -Wno-cast-qual -Wwrite-strings -c dis-cil.cdis-cil.c:44:2: error: #error Don't know how to implement isinf for this platform. #error Don't know how to implement isinf for this platform.  ^make[3]: *** [Makefile:442: dis-cil.o] Error 1make[3]: Leaving directory '/var/tmp/portage/dev-lang/mono-2.10.9-r2/work/mono-2.10.9/mono/dis'make[2]: *** [Makefile:340: all-recursive] Error 1make[2]: Leaving directory '/var/tmp/portage/dev-lang/mono-2.10.9-r2/work/mono-2.10.9/mono'make[1]: *** [Makefile:415: all-recursive] Error 1make[1]: Leaving directory '/var/tmp/portage/dev-lang/mono-2.10.9-r2/work/mono-2.10.9'make: *** [Makefile:340: all] Error 2emerge --info:skyrail ~ # emerge --info '=dev-lang/mono-2.10.9-r2::gentoo'                                                                                            [42/1827]!!!
