* | Provide build rules for a compatibility libraryUlf Hermann2017-05-081-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | We need to export open(), close(), malloc(), and free() from the C library we are using so that we can handle resources passed to and from elfutils correctly. For example, on Windows, calling free() on memory malloc()'d with a different C library will not work. In addition, having __cxa_demangle from the GNU libstdc++ available is very helpful, so we include that, too.

* | Skip fchown, fchmod, fadvise, fallocate if functions are unavailableUlf Hermann2017-05-041-0/+5
| | | | | | | | | | | | | | | | | | | | | | If fchmod or fchown are unavailable, then the file permission model is likely to be different from what we expect there. posix_fallocate is a rather fragile affair already on linux, and not guaranteed to do anything useful. If it's not available, the result will be the same as when it's available and unreliable. fadvise is an optimization.

* | Add our own tdestroy if search.h exposes a node_t structUlf Hermann2017-05-041-0/+5
| | | | | | | | | | | | | | | | | | | | | | tdestroy is not necessarily available from search.h, but we need it. gnulib cannot help us here as it will detect search.h to be available and functional in that case. However, some search.h expose a node_t struct which can be used to implement tdestroy. If that is the case, add an implementation to libgnu.a.

* | Check native binary formatUlf Hermann2017-05-021-0/+4
| | | | | | | | | | | | | | | | | | | | If our native binary format is not ELF, there is no point in doing the textrel check and we have to exclude some tests that compile source code with the native compiler and then check something on the resulting binary with elfutils.

* | Generalize library namesUlf Hermann2017-04-281-0/+5
| | | | | | | | | | | | | | | | | | On windows library names end with ".dll" and the prefix "lib" us usually omitted. Take this into account and also drop the $(EXEEXT) workaround. We don't need to use noinst_PROGRAMS as there is also noinst_DATA. Change-Id: I7e4ba2432811d5ad85051ea0c9d5674eabf79b3c Reviewed-by: Christian Kandeler <christian.kandeler@qt.io>

| | | | | | | | | | | | | | | | | | On windows those aren't needed because the link results are no ELF files and all code is position independent anyway. gcc then complains about them, which is in turn caught by -Werror.

| | | | | | | | | | | | | | | | | | mempcpy, memrchr, rawmemchr, and argp are provided by gnulib now. We don't need to define them locally and we don't need to search for an external libargp.

| | | | | | | | | | | | | | | | | | | | This enables us to build a fully featured elfutils package on systems with reduced C libraries, such as windows. All the modules are built into libgnu.a, which is then linked into all binaries if --enable-gnulib is given on the configure line.

* Add -D_FORTIFY_SOURCE=2 to CFLAGS if possible.Mark Wielaard2017-02-141-0/+4
| | | | | | | | | Some distros now add -D_FORTIFY_SOURCE=2 by default and we have missed some issues in the past caught by it. Add it to CFLAGS if possible.

* Only workaround fts.h if we have a bad version that doesn't handle LFS.Mark Wielaard2016-11-231-0/+5
| | | | | | | | | | Older versions of glibc included an fts implementation that didn't have Large File System support. We worked around that in linux-kernel-modules.c by including it early before config.h and then redefining some symbols to get the 64-bit versions. This is somewhat fragile and not necessary with newer glibc. If possible we want the 64bit fts version always. Signed-off-by: Mark Wielaard <mjw@redhat.com>
* Add GCC7 -Wimplicit-fallthrough support/fixes.Mark Wielaard2016-11-101-1/+6
| | | | | | | | | | | GCC7 will have a new -Wimplicit-fallthrough warning. It did catch one small buglet in elflint option procession. So it seems useful to enable to make sure all swatch case fallthroughs are deliberate. Add configure check to detect whether gcc support -Wimplicit-fallthrough and enable it. Add fixes and explicit fallthrough comments where necessary. Signed-off-by: Mark Wielaard <mjw@redhat.com>

* config: Pass the compiler -Werror during warning detectionFilipe Brandenburger2016-05-031-0/+3
| | | | | | | | | | | | | | Otherwise the compilation prints a warning but exits with 0 return code. However, later during the compilation, when -Werror is enforced to about every file, the unsupported options start breaking the builds. Tested: Ran configure with clang-3.5 and built libelf/ tree with it. $ autoreconf -i $ ./configure CC=clang-3.5 ... $ make -C libelf Signed-off-by: Filipe Brandenburger <filbranden@google.com>
* config: Fix check for argp_parse to pass &argvFilipe Brandenburger2016-05-021-0/+4
| | | | | | | | | | | | | | | | | | | Right now it's passing a char* when it expects a char** instead. This usually produces a warning that may go unnoticed, but if CFLAGS contains -Werror, that breaks the ./configure run with the following error: $ ./configure CFLAGS=-Werror ... configure: WARNING: "libc does not have argp" checking for argp_parse in -largp... no configure: error: "no libargp found" Tested: Checked that after this fix, running ./configure CFLAGS=-Werror works as expected and argp_parse is correctly detected.

* config: Use --program-prefix=eu- by default.Mark Wielaard2016-03-021-0/+5
| | | | | | | | | | | | We want eu- as default program prefix if none was given by the user. But if the user explicitly provided --program-prefix="" then pretend it wasn't set at all (NONE). This makes sure all tools will be installed as eu-<program>. We want this default since most tools would normally conflict with the GNU binutils variants that have similar names.

| | | | | | | | | Both -Wlogical-op and -Wduplicated-cond may produce useful warnings. But we have to check them first. Older versions of gcc had a -Wlogical-op that warned on some constructs using macros that are not erronious. Only GCC6 has -Wduplicated-cond. Signed-off-by: Mark Wielaard <mjw@redhat.com>

* Define MODVERSION in a more reproducable way.Mark Wielaard2015-06-051-0/+5
| | | | | | | | | We define MODVERSION to make sure the libebl backend modules match the elfutils build when we dlopen them. Using hostname and date makes it very hard to create reproducable builds.

| | | | | | | | | | | | Now that we are -fsanitize=undefined clean make sure we keep it that way. We do have to disable alignment checking. Because we might explicitly use unaligned accesses (see ALLOW_UNALIGNED). Rename DISTCHECK_CONFIGURE_FLAGS to AM_DISTCHECK_CONFIGURE_FLAGS, so the user can override. And add --enable-sanitize-undefined. Signed-off-by: Mark Wielaard <mjw@redhat.com>
