Re: [Linux-gpib-general] Detecting the absence/removal of board (USB device)

Apparently for php 8 ... - TSRMLS_CC was part of the the Thread-Safe Resource Manager, an implementation of thread-local storage used to build PHP for multi-threaded environments. It has been removed because newer mechanisms exist to do the same thing much more transparently. You can safely remove all uses of TSRMLS_* from your extension, unless you need to retain PHP 5 support. https://github.com/php/php-src/blob/PHP-8.0/UPGRADING.INTERNALS On Sunday, February 27, 2022, 09:18:01 PM EST, Michael K via Linux-gpib-general <lin...@li...> wrote: maybe a php version problem? php -vPHP 8.0.16 (cli) (built: Feb 15 2022 21:34:32) ( NTS gcc x86_64 )Copyright (c) The PHP GroupZend Engine v4.0.16, Copyright (c) Zend Technologies with Zend OPcache v8.0.16, Copyright (c), by Zend Technologies On Sunday, February 27, 2022, 09:13:20 PM EST, Michael K via Linux-gpib-general <lin...@li...> wrote: If I use "YACC=bison" on the configure that problem is solved but now I get a stack of other errors ... like gpib.c: In function ‘zif_iberr’:gpib.c:73:45: error: expected ‘)’ before ‘TSRMLS_CC’ 73 | if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "") == FAILURE) \ | ~ ^~~~~~~~~gpib.c:430:6: note: in expansion of macro ‘FUN_ACCESSOR’ 430 | FUN_ACCESSOR(iberr) | ^~~~~~~~~~~~gpib.c:73:7: error: too few arguments to function ‘zend_parse_parameters’ 73 | if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "") == FAILURE) \ | ^~~~~~~~~~~~~~~~~~~~~gpib.c:430:6: note: in expansion of macro ‘FUN_ACCESSOR’ 430 | FUN_ACCESSOR(iberr) | ^~~~~~~~~~~~In file included from /usr/include/php/main/php.h:35, from gpib.c:65:/usr/include/php/Zend/zend_API.h:304:22: note: declared here 304 | ZEND_API zend_result zend_parse_parameters(uint32_t num_args, const char *type_spec, ...); | ^~~~~~~~~~~~~~~~~~~~~gpib.c: In function ‘zif_ibcnt’:gpib.c:73:45: error: expected ‘)’ before ‘TSRMLS_CC’ 73 | if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "") == FAILURE) \ | ~ ^~~~~~~~~gpib.c:431:6: note: in expansion of macro ‘FUN_ACCESSOR’ 431 | FUN_ACCESSOR(ibcnt) | ^~~~~~~~~~~~gpib.c:73:7: error: too few arguments to function ‘zend_parse_parameters’ 73 | if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "") == FAILURE) \ | ^~~~~~~~~~~~~~~~~~~~~gpib.c:431:6: note: in expansion of macro ‘FUN_ACCESSOR’ 431 | FUN_ACCESSOR(ibcnt) | ^~~~~~~~~~~~In file included from /usr/include/php/main/php.h:35, from gpib.c:65:/usr/include/php/Zend/zend_API.h:304:22: note: declared here 304 | ZEND_API zend_result zend_parse_parameters(uint32_t num_args, const char *type_spec, ...); | ^~~~~~~~~~~~~~~~~~~~~gpib.c: In function ‘zif_ibsta’:gpib.c:73:45: error: expected ‘)’ before ‘TSRMLS_CC’ 73 | if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "") == FAILURE) \ | ~ ^~~~~~~~~gpib.c:432:6: note: in expansion of macro ‘FUN_ACCESSOR’ 432 | FUN_ACCESSOR(ibsta) | ^~~~~~~~~~~~ On Sunday, February 27, 2022, 09:00:41 PM EST, Michael K via Linux-gpib-general <lin...@li...> wrote: That's great but I'm now having trouble compiling the SVN.
