19 # --host=i686-w64-mingw32 Use the mingw cross-compiler to build a 'native' windows binary
20 # --enable-mingw32 Use mingw32 for a Windows GUI
21 # --enable-static-linking Use static linking instead of dynamic linking (and not have
22 # to put all the .DLLs in the path or the same dir as Privoxy)
23 # --disable-pcre2 Don't try to use the pcre2 library even if it's available
24 # --disable-pthread Use native threads instead of POSIX pthreads library
25 # --disable-dynamic-pcre Use the built-in, static pcre, even if libpcre is available
26 # --with-docbook=yes Enable docbook documentation creation

45 # 'make 2>&1 | tee log.make'
47 CFLAGS="${CFLAGS} -fstack-protector-strong -D_FORTIFY_SOURCE=2"
48 LDFLAGS="${LDFLAGS} -fstack-protector-strong"
49 # -fstack-protector-strong: enable stack checking.
50 # NOTE: need to specify when compiling _and_ linking
51 # stack-protector-strong: better balance between security and performance.
52 # This flag protects more kinds of vulnerable functions than -fstack-protector does,
53 # but not every function, providing better performance than -fstack-protector-all.
54 # see : https://en.wikipedia.org/wiki/Buffer_overflow_protection
55 # NOTE: needs static linking or the following in the path:
56 # /usr/i686-w64-mingw32/sys-root/mingw/bin/libssp-0.dll
58 # -D_FORTIFY_SOURCE: detect some buffer overflow errors
59 # ***>> requires compiler optimization level 1 or above <<***
60 # see : https://gcc.gnu.org/legacy-ml/gcc-patches/2004-09/msg02055.html
61 # The difference between -D_FORTIFY_SOURCE=1 and -D_FORTIFY_SOURCE=2 is e.g. for
62 # struct S { struct T { char buf[5]; int x; } t; char buf[20]; } var;
63 # With -D_FORTIFY_SOURCE=1,
64 # strcpy (&var.t.buf[1], "abcdefg");
65 # is not considered an overflow (object is whole VAR), while with -D_FORTIFY_SOURCE=2
66 # strcpy (&var.t.buf[1], "abcdefg");
67 # will be considered a buffer overflow.
69 ### CFLAGS="${CFLAGS} -march=native"
71 # Generate instructions for the machine type cpu-type. In contrast to -mtune=cpu-type, which merely tunes the
72 # generated code for the specified cpu-type, -march=cpu-type allows GCC to generate code that may not run at all on
73 # processors other than the one indicated.
74 # Specifying -march=cpu-type implies -mtune=cpu-type.
77 # This selects the CPU to generate code for at compilation time by determining the processor type of the compiling
78 # machine. Using -march=native enables all instruction subsets supported by the local machine (hence the result
79 # might not run on different machines). Using -mtune=native produces code optimized for the local machine under
80 # the constraints of the selected instruction set.
