问PHP oci8不能通过pecl安装："fatal error: oci8_dtrace_gen.h“

EN

$ export PHP_DTRACE=yes
$ pecl install oci8

$ sudo yum install php-pear php-devel
$ pear download pecl/oci8 
$ tar xvzf oci8-2.1.8.tgz 
$ cd oci8-2.1.8/
$ phpize
# make sure of the instantclient path below... mine was version 18.3 so it was located in this folder... Also make note some tutorials ask for the ORACLE_HOME folder which theoretically is /usr/lib/oracle/18.3/client64 but if its instantclient then put the lib folder underneath it (worked for me at least:)
$ ./configure --with-oci8=instantclient,/usr/lib/oracle/18.3/client64/lib
$ make 
$ make install
#NOW an .so file built in: /usr/lib64/php/modules/oci8.so
#THIS STEP NOT NEEDED if SELinux disabled on your server/box, but if SELinux is enabled run: setsebool -P httpd_execmem 1
#NOW add:     extension=oci8.so     at the bottom of your php.ini file (probab in /etc/php.ini)
$ sudo service httpd restart
# note that you can also install PDO_OCI to connect to oracle but its very old and not as good as OCI8 lib (and maybe dependent on having OCI8 anyway)

Beforehand you may want to test and make sure the instantclient libs installed correctly by trying sqlplus:

$ sudo rpm -ivh oracle-instantclient18.3-basic-18.3.0.0.0-1.x86_64.rpm
$ sudo rpm -ivh oracle-instantclient18.3-sqlplus-18.3.0.0.0-1.x86_64.rpm
$ sudo rpm -ivh oracle-instantclient18.3-devel-18.3.0.0.0-1.x86_64.rpm
$ sudo rpm -ivh oracle-instantclient18.3-tools-18.3.0.0.0-1.x86_64.rpm
#add your TNSNAMES connection string info below to this file
$ sudo touch /usr/lib/oracle/18.3/client64/network/admin/tnsnames.ora 
$ vi ~/.bash_profile
#add below info to bash_profile to test sqlplus
ORACLE_HOME=/usr/lib/oracle/18.3/client64
export ORACLE_HOME
PATH=$PATH:$ORACLE_HOME/bin
export PATH

# log out and log back in and test, sqlplus should have access to TNS_ADMIN now
$ sqlplus username/pass@TNSNAMES_SHORTCUT_OF_THE_DB_CONNECTION

<?php

//works
// ... as long as $TNS_NAMES is defined and passed to apache correctly (using /etc/sysconfig/httpd to add the var.... after defined ORACLE_HOME in there, DONT USE $ORACLE_HOME to define the rest of the vars like for TNS_ADMIN... aka dont do this: TNS_ADMIN=$ORACLE_HOME/lib/network/admin ... use full path: TNS_ADMIN=/usr/lib/oracle/18.3/client64/lib/network/admin )
$username = "myusername";
$password = "mypassword\$2"; //note: may need to escape some chars here like for me i had to escape $ with a backslash
$db = "TNSNAMES_SHORTCUT_OF_THE_DB_CONNECTION";
