This option could also be read and set from a running program using ei_get_tracelevel(void) and ei_set_tracelevel(int).</p> <p> Own Id: OTP-5037</p> </item> <item> <p>Cross compilation improvements and other build system improvements.</p> <p>Most notable:</p> <list><item> Lots of cross compilation improvements. The old cross compilation support was more or less non-existing as well as broken. Please, note that the cross compilation support should still be considered as experimental. Also note that old cross compilation configurations cannot be used without modifications. For more information on cross compiling Erlang/OTP see the <c>$ERL_TOP/INSTALL-CROSS.md</c> file. </item><item> Support for staged install using <url href="http://www.gnu.org/prep/standards/html_node/DESTDIR.html">DESTDIR</url>. The old broken <c>INSTALL_PREFIX</c> has also been fixed. For more information see the <c>$ERL_TOP/INSTALL.md</c> file. </item><item> Documentation of the <c>release</c> target of the top <c>Makefile</c>. For more information see the <c>$ERL_TOP/INSTALL.md</c> file. </item><item> <c>make install</c> now by default creates relative symbolic links instead of absolute ones. For more information see the <c>$ERL_TOP/INSTALL.md</c> file. </item><item> <c>$ERL_TOP/configure --help=recursive</c> now works and prints help for all applications with <c>configure</c> scripts. </item><item> Doing <c>make install</c>, or <c>make release</c> directly after <c>make all</c> no longer triggers miscellaneous rebuilds. </item><item> Existing bootstrap system is now used when doing <c>make install</c>, or <c>make release</c> without a preceding <c>make all</c>. </item><item> The <c>crypto</c> and <c>ssl</c> applications use the same runtime library path when dynamically linking against <c>libssl.so</c> and <c>libcrypto.so</c>. The runtime library search path has also been extended. </item><item> The <c>configure</c> scripts of <c>erl_interface</c> and <c>odbc</c> now search for thread libraries and thread library quirks the same way as <c>erts</c> do. </item><item> The <c>configure</c> script of the <c>odbc</c> application now also looks for odbc libraries in <c>lib64</c> and <c>lib/64</c> directories when building on a 64-bit system. </item><item> The <c>config.h.in</c> file in the <c>erl_interface</c> application is now automatically generated in instead of statically updated which reduces the risk of <c>configure</c> tests without any effect. </item></list> <p>(Thanks to Henrik Riomar for suggestions and testing)</p> <p>(Thanks to Winston Smith for the AVR32-Linux cross configuration and testing)</p> <p> *** POTENTIAL INCOMPATIBILITY ***</p> <p> Own Id: OTP-8323</p> </item> <item> <p> Change erroneous "\\0" in documentation files <c>erl_notes.xml</c> and <c> erl_eterm.xml</c>.</p> <p> Own Id: OTP-8326</p> </item> <item> <p> Allow <c>erl_match()</c> to match <c>ERL_LONGLONG</c> and <c>ERL_U_LONGLONG</c> terms (Thanks to Scott Lystig Fritchie).</p> <p> Own Id: OTP-8400</p> </item> </list> </section> </section> <section><title>Erl_Interface 3.6.4</title> <section><title>Improvements and New Features</title> <list> <item> <p> The documentation is now built with open source tools (xsltproc and fop) that exists on most platforms. One visible change is that the frames are removed.</p> <p> Own Id: OTP-8201</p> </item> </list> </section> </section> <section><title>Erl_Interface 3.6.3</title> <section><title>Fixed Bugs and Malfunctions</title> <list> <item> <p> The manual states that erl_receive() return the reason in the <c>ErlMessage</c> struct. This was not the case and the function is now corrected.</p> <p> *** POTENTIAL INCOMPATIBILITY ***</p> <p> Own Id: OTP-4969</p> </item> <item> <p> In <c>send_exit.c</c> an errorneous size of memory allocation could occur when reallocating a buffer.</p> <p> In <c>ei_decode_trace.c</c> the index could be updated when the decoding failed.</p> <p> In <c>ei_printterm.c</c> the index could be updated when the decoding failed in lists and tuples.</p> <p> In <c>ei_decode_term.c</c> when decoding a double (ERL_FLOAT_EXT) no check was done to ensure that the last of the 31 bytes was null terminated.</p> <p> In <c>ei_decode_term.c</c> when decoding references, only the first 3 bytes are read, but the index did not increment by the total size.</p> <p> In <c>ei_decode_fun.c</c> no check of correct buffer allocation or data length was done.</p> <p> In <c>ei_decode_string.c</c> the integer list string case did not decode the NIL tail correctly.</p> <p> These errors has now been fixed. (Thanks to Romain Lenglet, Paul Mineiro and Paul Guyot).</p> <p> Own Id: OTP-6117</p> </item> <item> <p> <c>ei_decode_big</c> could be decoded with a garbage byte.</p> <p> <c>ei_encode_big</c> and <c>ei_x_encode_big</c> is now available.</p> <p> Own Id: OTP-7554</p> </item> <item> <p> The function <c>erl_init_resolve()</c> did not conform to C99 standard which caused a build error on some platforms. This has now been fixed.</p> <p> Own Id: OTP-8093</p> </item> <item> <p> <c>Makefile.in</c> has been updated to use the LDFLAGS environment variable (if set).
